If someone just cannot find lasting forgiveness for their abuser and they take the life of there abuser and then forgive them from the peace they receive from getting retribution is that worse than just never taking the life but struggling to forgive?

Keep in mind our minds are not the same as God. We may think that someone wanting to do something but holding back is less guilty than if they act on it. But scripture clearly states that Unforgivness from us will stop God from forgiving any of our sins. So in theory, the victim could commit murder then with the peace they get from the justice then forgive the abuser much easier. Then he could repent from murder, be forgiven, and best of all- there is no Unforgivness on his or her own part to hold Gods forgiveness away. I know that the original victim would risk encountering legal issues but I’m talking about what would be least damaging spiritually for them.

- there is no one at risk of getting hurt lmao I’m only posting this because I noticed a loop hole it biblical logic and wanted to see perspectives.
