The tragedy of David Gallant is that he essentially sublimated everything he held dear about himself - his hobbies, his desires, even his self-respect, in order to become another textbook self-flagellating male feminist who also happens to be a sexually-confused idiot who comes across as a creeper. At any point in time, he could have turned shit around. At any point in time, he could have saved himself. He didn't, even when he knew what he was doing was wrong.
In fact, that's the hallmark of Daveykins: That he felt he could get more and more ingratiated into the good books of his allies, if only he became the most ardent fighter on their side. That's why he was always in the vanguard for CON, that's why he was constantly pushing for escalation during GG, and that's why, ultimately, he was unpersoned by his own side. Even now, he pretends he cannot fathom that his own side willingly grouped him in the same camp with his enemies when he was always the most faithful.
Under it all, with David Gallant, there's a percievable sorrow behind his actions, and it doesn't take much to see why: David Gallant has come face to face with the fact that his alleged virtue is naught but a sham, played upon himself most of all. He would be pitiable, were he not such a fucking asshole.
