Why are most people unworthy of hate?

Simply because they have a loving nature and possess many virtues, including ethical and moral ones. Would you believe or trust someone with a deceitful, irresponsible, cruel, selfish or stingy disposition? Or one who is just the opposite. If you cannot find fault with the latter in most things, then he is worthy only of love. But i think that being ignorant or naive in certain things should not give you a reason to hate him, because no one is capable of being knowledgeable in all, or even most things. :-))
