It's weird, kinda like having a wife was the one constraint keeping him attached to the "normal, everyday life." As bizarre the situation surrounding her death is, along with the fact that he almost certainly killed her on purpose (murder) (whether she wanted him to or not) it probably did function as an extremely liberating event to him.

That liberation combined with the drugged out memories of murdering your wife, plus the fact that you'd been forced into temporary exile... it's easy to see how something like that could give you a lifetime of material to draw upon.
