I suppose this aspect of it is part of a larger "is it okay to cause problems with your role-playing choices?" discussion. Personally, I think it can be fun to some degree (the hot-tempered character occasionally causing problems with an NPC by having an outburst, for example) but it can admittedly be tricky to balance so that everyone's happy.
