Jesus gave us a New Commandment at John 13:34-35.Since God decides what is wrong or not, the point is moot. He can kill whoever he wants and call it justice can he not?
In God's Golden Rule of Leviticus 19:18 we are to love neighbor as self.
In Jesus' New commandment we are to have the same self-sacrificing love for others as Jesus has.
In other words, we are Now to love neighbor ' more ' than self, more than the Golden Rule.
God knows who wants to have self-sacrificing love for Him and others.
So, it is only the 'wicked' who will be ' destroyed forever ' as per Psalms 92:7
