It doesn't have any logic behind it, though. His intention is to come in and steal all of your things, not to kill anybody. If he were suicidal and wanted to bring people down with him, he would not go into somoene's house to steal things and then threaten to blow himself up if anyone tried to stop him. Why would he even bother to steal things if he was just going to blow himself to bits?
Does this mean you would destroy your house on top of the robber?
I think so. After all, didn't you see the dude wearing a hat made of bread sticks? And the message in the picture? If you did, Im pretty sure he would break the house and the robber in it. I think..
