That's a matter for the police not your deity.
Does the bible say anything about ones especially a fellow Christian who damages another property and refuses to pay for it and act like it never happened?
Wasn't that the 121st Commandment?
"Thou shalt not damage another's property and refuse to pay for it and act like it never happened, unless it's April Fool's Day and you're just joking, of course. Then it's permissible, but don't do it very often or nobody will be surprised anymore and nobody will think it's funny."
Jesus stated this at Matthew 7:12, " All things, therefore, that you want men to do to you, you also must do to them. This, in fact, is what the Law and Prophets mean." Only if we treat others in this way can we prove that we are true followers of Jesus Christ. The law made it clear that God's people were to be just. Not everyone who say they are followers of Jesus are, that is why that person may be refusin to pay.
There's the saying.... Do unto others .....That should suffice.
Yes, the regarding the Bible and "Forgiveness" . . . Some of the Bible is for it, . . . Unless it unleashes God's Wrath, and then it is definitely against it . . . A lot of the OT is really against it.
Most doctrines would tell you to forgive you brother/sister . . . . Consider using Empathy, and Reciprocity to handle the situation . . .
