To be fair, he didnt steal anything (that I'm aware of). He just simply accepted stolen money, iron, diamonds, and many other things.
Understandably, he is angry that he lost all "his" stuff (even though it originally belonged to someone else). I can also understand why he's mad that he lost part of his town, and all his other stuff that he actually gathered (though, he dug up his dirt, sand, sandstone, cobble, and gravel with iron tools, which originally belonged to caprica).
As I told Crunchy before, everybody lost in this situation. Caprica lost because we are missing tons of stuff (most of it will never be recovered, such as the iron, gold, and diamonds). Rawbeefcake lost because he got banned. And Crunchywalnut lost because because part of his town is gone and he lost all his chests.
