he was using his penance stare at that time, yes. He was in a situation he never encountered before and was on the defensive.
It's not a permanent thing.
And honestly, I can't fix things you don't tell me. So go ahead and list them all. I can always, iunno, tone him down a bit? Give him more limitations? Maybe since he's away from mephisto's reach he cannot use his penance stare for more than a few minutes. 
I'd much rather be told what makes people not like him then just know people don't like him. It's crap like this that makes me leave roleplays.
