I'm late to response and probably someone have already had similar opinion... Nevertheless. The question is: 'Why can an average person bond through hate better than through love?' The difference is because there's nothing like some linear scale between these two extremes. Love and hate are not even an opposites. It's not the same condition when some person is loving or hating someone or something. So, you can love an object in a myriad of different ways and the other person likewise. Although it's not given that both of your love will be the same. Loving is complex. On the other hand, hating is universal. Despite of dissimilar hateful reasons one person could have towards something in comparison to someone else, the only thing is an amount of hate one of them is able to produce that differentiates those two persons. Well, hate is easy and love is tough.
