I will just paste what I found on WT Lib for your thoughts:

Proverbs 16:4 (AS) states: “Jehovah hath made everything for its own end; yea, even the wicked for the day of evil.” Does this mean that Jehovah makes men wicked, perhaps to fit some supposed predestination of his?—D. U., United States.
Jehovah does not create men wicked to fit in with the doctrine of predestination, for that doctrine is a false teaching. (See the May 15 and June 1, 1953, issues of The Watchtower.) And not for a day of evil nor for any other reason did Jehovah make the wicked. To argue so would be to contradict Deuteronomy 32:4, 5 (NW) and Ecclesiastes 7:29 (Le), which texts read: “The Rock, perfect is his activity, for all his ways are justice. A God of faithfulness, with whom there is no injustice; righteous and upright is he. They have acted ruinously on their own part; they are not his children, the defect is their own. A generation crooked and twisted!” “Lo, this only did I find, that God hath made man upright; but they have sought for many (sinful) devices.”
The same Hebrew word here in Proverbs 16:4 translated “made” is translated “ordaineth” at Psalm 7:13: “He ordaineth his arrows against the persecutors.” They are appointed for use against enemies. In the same way, the wicked are ordained or appointed for destruction in the day of evil, a day that will be evil to them because it will mark the end of their existence. As a class the wicked are made to exist or remain till then, Jehovah knowing how to reserve them or make them remain till that time of his vindication: “Jehovah knows how to deliver people of godly devotion out of trial, but to reserve unrighteous people for the day of judgment to be cut off.” (2 Pet. 2:9, NW) It is this thought that is given by the Septuagint translation of Proverbs 16:4: “All the works of the Lord are done with righteousness; and the ungodly man is kept for the evil day.” The evil day is for the wicked, and the wicked are for the evil day.

Jehovah has made “even the wicked one for the evil day.” (Proverbs 16:4b) He did not create the wicked, for “perfect is his activity.” (Deuteronomy 32:4) However, he has allowed them to come into existence and continue living until he sees fit to execute his adverse judgment. For example, Jehovah said to Pharaoh of Egypt: “For this cause I have kept you in existence, for the sake of showing you my power and in order to have my name declared in all the earth.” (Exodus 9:16) The Ten Plagues and the destruction of Pharaoh and his forces in the Red Sea were indeed memorable demonstrations of God’s matchless power.
