Probably more in Drift AU than main TAUverse or FWTB. For the most part, if Dipper feels himself beginning to… drift, he’ll leave the room for awhile until he calms down and does something he’ll regret.
(The same thing goes for roughhousing with the kids, when he catches his claws beginning to sharpen again, his movements become hungrier-)
That being said, the triplets do make a few ‘bad’ deals with Dipper, mainly as Dipper and their parents and Stan see it as a good teaching experience in a mostly safe environment.
Babies may be tempted with a demon uncle to wheel and deal, but they learn quick.
