The only way we can come to a correct understanding of any scripture is by knowing;
1) Who wrote it and when it was written
2) The context said before and after the passage, well surrounding it
3) Through reading, studying the meaning of & understanding the rest of the scriptures.
About any scripture, once it's been isolated from all the other important information in the Bible needed to be equipped to correctly understand it & know what it's full meaning for Christians today is, could be misunderstood & wrongly applied to mislead someone from it's real meaning.
First thing we need to know is: If a scripture was/is a command from God or Jesus, or if it was quoted from those sources, as something we must do? Or if it was general guidance given by someone else, maybe an apostle who was inspired by God, yet it is not a direct command (to do something or refrain from doing something) that a person MUST do in order to please God & gain everlasting life? In other words, there are a lot of scriptures that gave common sense guidance on how to deal with many new issues the early Christians were navigating. The early Christians had to decide among the different cities & congregations what their unified stance would be regarding a lot of everyday living issues they'd never had to make decisions on before Jesus had come & been resurrected. As descendants of Abraham so many of them knew & adhered to the laws their parent's had handed down to & taught them. Some Gentile members had never observed the Mosaic law or any religious beliefs. So in order to unite them better, basic principles were given by Paul and others for the new Christians to remember and keep in mind to aid them to make wise decisions for themselves in matters of living. But they were not given as commands to follow. There are differences between the commands and the guidance given. There are statements in the Bible that pagan Kings said, yet they weren't recorded as commands of God or Jesus for us.
As imperfect human beings, we're easily influenced by what or whoever we're in close association with too much. It'll influence us, even if we try hard & are determined we won't allow anything to affect us, even if we believe we're far too strong in our faith, love for God & Jesus and our family to ever allow ourselves to be influenced in negative ways, still, in weak moments, we're vulnerable. When worn down or depressed by the death of someone we love, or by being fired or facing other really hard things, that's when we're most vulnerable to failing.
Two scriptures that warn us against thinking we're immune to falling are : "Pride goeth before a fall" (Proverbs 16:18) "Let he who thinks he is standing take heed lest he fall." (1 Corinthians 10:12).
I do think there are times when the Governing Body of JW has taken guidance & turned it into hard & fast rules or commands that JW's must abide by, or where they have taken a scripture & applied it in ways it may not ever have been intended to be applied to Christians, but not with any malice or intention to deceive anyone, so much as, it's happened out of an overabundance of zeal for the moral excellence of the whole group of JW's. At times, scriptures don't necessarily spell things out nor command that a behavior is or is not practiced by a Christian, yet it made logical sense to adhere to certain restrictions. Is this right or wrong? I can't say, as they indeed do run the organization & are in place to guide & teach all & to make those decisions that aren't specifically written out exactly in the scriptures. So it has been their charge and their right to prayerfully decide on such matters, much like Paul did in his time render decisions & give guidance on matters for all the congregations, after seeking God's guidance themselves.
I will say this, though, in addition, no JW becomes one & gets baptized without already being fully aware of all that they're expected to do and not do as one of JW's. Years of Bible study and several oral tests you must pass about what they believe and adhere to, where you have to also demonstrate that you know and can find in the Bible where supporting scriptures are that tell you why they do this or that or why they do not, are part of the requirements so.... it's not as if those joining are deceived or fooled about anything they're agreeing to because the process is an involved one to actually be approved as a candidate ready to get baptized, and be a JW. They ensure you have thorough understanding so no one is duped or misled in any way.
