Love/Hate Relation

I remember watching the anime "Naruto". There were two rival clans and a boy from each just so happen to become friends and rivals. Of course the views differed the yin and yan relationship ship. One of them, had a dream about how he would achieve peace and the other had his own. Both methods had it's merits of course one is preferred over the other and the other is the enemy. Because these two men grew up together as friends and rivals despite the fact that they were enemies the one seen as the good one still had respect for him as he understood his past and the circumstances. 

The "bad" one descended from a clan who had ocular power and the other had their own body enhancement doesn't go too much into depth of what it is. They both clans different in their methods with the Uchiha, having a bit of a darker and blood stained past.  Suffice to say they do not have the best track record and so there is an assumption that because he is from that clan it is to be expected that he also embodies all these negative traits of his clans past.

I believe one of them refers to his clan as a clan filled with hatred. Though his rival's brother interjects and says that that is not true, that out of all the clans the Uchiha are in fact the ones with the greatest love. That the very reason that the clan seems so hateful because their love is so strong that when tragedy strikes the rage and the hates is that much stronger as well. That the potential on one side is the potential on the other. Same side of the same coin, the tree that reaches into heaven must be rooted in hell type of analogy.

It makes sense in a way if you do not care much about something when it is taken away you do not get all that angry. The greater the love that is taken away the more pain the more of the flip side that will in turn produce. I'm not sure if it's from the same show but I've also heard that hate is love when it is not reciprocated. It's an interesting thought, the fact that all the hate in the world could possibly just be love that went wrong.
