I just think that his default is to be honourable despite what he's done in the past so I find it easy to play him as a good character, there are plenty of bad guys to **** around with.
If you play as bad does he still kick Her Strauss out of the camp or does he not help the widow or the family where he catches the bronchitis from?
I can't imagine him not doing those things. Might have to try hard to be bad. Surely he would also get on with a Micha and then not get on with others. Interested now.
