He was PvPing with his friend for fun probably, and he was really acting nice about it afterwards in the tells.

I would give it back, people make misstakes, and even if its not super valuable anymore, he still feels really bad about it.

What if it was a Cerberus member this happened to...

I would give it back, mind you in the case "if it happened to you", the person would probably keep or auction it, but still, I would of givin it back hehe.
