Depends if he hurt anyone during the robbery or not. If not, then I would ignore it.

In this case as Banks have alot of money anyway I would not report the robber for trying to do the right thing and help the orphanage.

report him

stealing is stealing

it would likely go on the news etc, he'd try to plead that he was just trying to help, people would think he was a hero, some would think he's a thief. either way, people would find out about the orphanage and then people would try to donate money
