Motoyuki seemed to have childhood issues, experienced parental abuse and domestic violence.
Gomi doesn't have that, but he really is a weirdo with incel adjacent thoughts and self hating tendencies. And like someone else said, he jacks off to weird porn and loli porn.
I think the cycle will continue and that woman seems to fucking LIVE for that cycle of being saved and abused. Gomi probably won't abuse her the same exact way Motoyuki did, but he probably will be a scumbag.
It's in his name...
