I wasn't being facetious at all. I really do think he started out as a dumpster diver in space but took on the persona of noble manly hero when he rescued Kes. Probably his first time ever playing that role, so quite an ego boost. Add in that he was living in luxury on Voyager and he just won the lottery. That was a lot he had to lose and you see him get quite nasty about it, possibly reverting to survival mode that he was in while living through war. Maybe it was all PTSD.
