I do really agree with what @Tekk had to mention. Septik's proneness to anger was a major concern of mine when considering him for staff ages ago and an issue I really doubt would ever totally go away. Despite that, I still trusted him enough to promote him. I don't think he's ever actually caused any major issues because of it and even though he has lashed out in the past I do think he's level headed enough to keep himself in check. It's something he needs to be self aware about but so long as he is then he should be capable of stopping himself from misbehaving and thinking twice as a staff member.
This isn't really a plus one, but I think, despite his temper, it's worth giving him a chance.
