Peace be with you.
Yes, it's true God's standards have always been the same. Men however have taken what God has said and twisted or corrupted it to suit their own ends. The WTBTS is very guilty of this. The unmerciful treatment fo their fellow worshippers clearly bear this out. They have no applied Jesus words at Matthew 9:9-13
9 As Jesus went on from there, he saw a man named Matthew sitting at the tax collector's booth. "Follow me," he told him, and Matthew got up and followed him.
10 While Jesus was having dinner at Matthew's house, many tax collectors and sinners came and ate with him and his disciples. 11 When the Pharisees saw this, they asked his disciples, "Why does your teacher eat with tax collectors and sinners?"
12 On hearing this, Jesus said, "It is not the healthy who need a doctor, but the sick. 13 But go and learn what this means: ‘I desire mercy, not sacrifice.'[a] For I have not come to call the righteous, but sinners."
Time and again we as Christians are told by Christ that mercy and love should be the empowering force that moves us to action in regards to the welfare of our fellow man (be they Christians or not). The GB have clearly not demonstrated love for the afflicted ones, ones suffering from depression, hard economic times, family problems etc. Their advice has always been to continue to give money, go out in field service, comment at meetings and study the WTS publications. They lack empathy. People are told to wait on Jehovah, yet if a person seeks professional help, be it medical or legal they are criticized by the GB for "running ahead" of Jehovah when this clearly isn't the case at all. The GB have set themselves up as Judge, Jury and Executioner as regards to administering discipline in the congregation and it's their way or not at all. The problem with this mentality of strict adherence to rules and regulations (many of which change with "New Light") leaves the congregations confused and bewildered as to what is the right course. Many witnesses have lost their lives due to the GB's ever changing doctrines and their refusal to admit responsibility when they have caused harm to others. They "blame" God and say it's "New Light" from him and thus cause people to lose faith in God.
Mark 2:23-28
.23 One Sabbath Jesus was going through the grainfields, and as his disciples walked along, they began to pick some heads of grain. 24 The Pharisees said to him, "Look, why are they doing what is unlawful on the Sabbath?"
25 He answered, "Have you never read what David did when he and his companions were hungry and in need? 26 In the days of Abiathar the high priest, he entered the house of God and ate the consecrated bread, which is lawful only for priests to eat. And he also gave some to his companions."
27 Then he said to them, "The Sabbath was made for man, not man for the Sabbath. 28 So the Son of Man is Lord even of the Sabbath."
Jesus here clearly shows that the Sabbath was made to be a benefit for mankind and not a burden. The Law covenant was made to show the Israelites that they couldn't come to God on their own, they needed a mediator, but the Law set them free from the corruption of the surrounding nations. The Pharisees and Sadducees (think modern day Governing Body) made the Law a burden to the people and created sub-laws and regulations for every aspect of life. The GB does the exact same thing. When I read Luke 12:40-48 I get that Jesus was talking about the GB directly in regards to the Evil Slave which make up only part of the FDS which isn't made up of just JW's and ex-JWs but worshippers of God from all over the world.
Luke 12:40-48 (New International Version, ©2010)
40 You also must be ready, because the Son of Man will come at an hour when you do not expect him."
41 Peter asked, "Lord, are you telling this parable to us, or to everyone?"
42 The Lord answered, "Who then is the faithful and wise manager, whom the master puts in charge of his servants to give them their food allowance at the proper time? 43 It will be good for that servant whom the master finds doing so when he returns.
44 Truly I tell you, he will put him in charge of all his possessions.
45 But suppose the servant says to himself, ‘My master is taking a long time in coming,' and he then begins to beat the other servants, both men and women, and to eat and drink and get drunk
46 The master of that servant will come on a day when he does not expect him and at an hour he is not aware of. He will cut him to pieces and assign him a place with the unbelievers.
47 "The servant who knows the master's will and does not get ready or does not do what the master wants will be beaten with many blows.
48 But the one who does not know and does things deserving punishment will be beaten with few blows. From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked.
In regards to God changing things He has said in the past:
When Jonah was sent to Ninevah to speak to the inhabitants about YHWH's judgment against them he was unaware that the potential for forgiveness existed. He thought it was cut and dry, that they would be destroyed no matter what. That wasn't the case and he became upset about it. God didn't change his decision regarding Ninevah, he simply didn't give Jonah all the information regarding his task and the possiblity of a different outcome based upon whther they repented or not.
In regards to the Law of Moses Jesus said:
New International Version (©1984)
Matthew 5:19
Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven.
Jesus also said:
(New International Version, ©2010)
Matthew 5:17
17 "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
Romans 10:14 "For Christ has already accomplished the purpose for which the law was given. As a result, all who believe in him are made right with God."
Jesus fulfilled the Law of Moses but he didn't destroy it because everything that is in the Law of Moses is also contained in the teachings of Christ. The Law was a tutor leading to Christ and so to gain salvation we no longer look to the Law of Moses, but rather the same Law in Christ.
The Law of Moses gave detailed requirements for the carrying out of sacrifices and observation of certain days. Are these still required. In my opinion, no. Simply put, the Temple no longer exists for it was destroyed by the Romans in 70 C.E. Without a Temple there can be no sacrifices. The Orthodox Judaism supports this notion themselves until the building of the Third temple which will commence with the arrival of the Jewish Messiah.

Jesus himself echoes this idea when speaking to the Samaritan woman in which he stated:
John 4:21
(New International Version, ©2010)
21 "Woman," Jesus replied, "believe me, a time is coming when you will worship the Father neither on this mountain nor in Jerusalem."
May you have peace,
