Not really. He's too much of a child himself to raise children.
Now, he was never abusive or violent, without provocation, in the way that so many are, in that he would never hit his wife or Lisa, but his repeated strangling of Bart shows a lack of emotional self-control. However he would never have done that if he had a kid like Milhouse or one of Flanders' kids. (He would have just mocked them and undermined their self-confidence.)
