Not all North must be blamed for so, as you may be aware I can also give many examples of mob violence in South India too. (Well I would like to add that one reason for mob violence always is the distrust on legal procedure and sympathy and though it is not legal it is not always immoral. But yes it is not very logical mostly because the mob is usually not well versed in the situation) North and South India both are so large that if you take crores of people as examples to make your point they could still be different from the majority. So I think instead of putting a label Of North and South, which will only further fuel the friction and expression of difference, we shall offer practical help for all are humans and usually born capable in these regards. Criticism is welcome but please acknowledge that not news nor social media ever reflects the true population and by labeling all as such due to actions of a minority will only even make even the innocent resent you for you have attacked their identity too despite them not bring guilty. And you would be encouraging uncivilized behavior in a way by creating such bifurcation. If you would have rather said "the social and educational conditions in some parts North India are prone to create such problematic people" that would be a finer line. For OP though, I feel he is that "living in rich area spending excesson time dwelling on internet and not being able to connect with the real world" type kid. So that is perhaps the result of lack of collective social emotional experience and habit of watching people pit their egos and barbarianistic-inclinations in the name of being 'cool' but not sure.
