And you can search on the internet, it is not enough to be remorseful for a crime, you have to return the full amount to benefit from it, remember when I say full amount, I mean the full amount along with the gain, because they will also demand the lost amount for that, inflation, and exchange rate are there for that.
So refunding them won't change anything. Don't act like a fool, and if you've done something, don't be afraid. If you're afraid, don't do it.
Enjoy yourself, that money will last you for a long time, as I said, you can send that amount to other people instead of returning it to him, and you can change their fucking lives.
But contacting him would be one of the biggest mistakes you can make.
