Some parts yes and some parts no. But a lot of it could have been solved a few ways

1. The dad kicks the ever living shit out of him. The kid needs to learn who the alpha is and that it’s the farther.
2. Send him to an institution permanently before he rapes and/or murders someone
3. Kick him out and threaten that if he ever gets near their daughter he’s a dead man walking.

When the underwear and sketchbook was found was when the farther needs to be willing to take the extreme steps. The kid needs help and is a permanent lost cause. In the last ten years we’ve seen what these type of people end up doing. He’s a danger to himself and everyone around him. It might be tough but the father needs to do what he needs to do to protect his stable family.

Call it cold, call it heartless, but if this kid took his incel shit out on your daughter you might find it to be necessary.
