I think he has convinced himself that his 'activism work' is so important that it overrides anything else that he does. He will bury the embarrassing or controversial stuff as much as he can, and use any mental gymnastics to rationalize his efforts to forget them. Mostly, he tries either blaming others, blaming the WTS for messing him up (mentally, psychologically, emotionally, penisly, etc), claiming that others are being unfair, or that they are no better than him, that the bad is offset by the good, and so on.
People like him, by the time they actually face up to who they are and what they have done, have built up so much baggage that it is likely to crush them. That, or they decide that they are irredeemable and embrace the role of the villain. I think he's still at a crossroads and either option remains a possibility.
