Hey, as you have done it will be done unto you. If he treated others cruelly it is righteous judgement that he be treated cruelly.
I'm not trying to get on anyone else's case about this. I just came to slowly realize over the years that I don't love people more than God and He is angry with the wicked every day. When there are wicked leaders and such who were responsible for killing innocent, ie I just got done reading 1 Kings again, I'm reminded that God had established laws with justice. Even though mercy applies to all of us, there are people like Jezebel were enemies of God.
I officiated the funeral of a friend recently, so I am still a little raw at the whole pandemic thing. She was a victim of the cancer shot.
I'm trying to be more selective on who I love and who I hate. It's toward the enemies of our Lord, not my personal enemies.
Psalm 139
"Do not I hate them, O LORD, that hate thee? and am not I grieved with those that rise up against thee? I hate them with perfect hatred: I count them mine enemies."
