There is a very interesting perspective, a Buddhist analysis of human nature. That our shortcomings – it can be hatred, it can be violence, in whatever form they arise – are due to three reasons.
And the three reasons are greed, hatred and delusion. So as long as we have these three characteristics, we will behave sometimes violently, sometimes irrationally, in all the ways human beings are behaving in this world.
When you see behaviour arising from greed, hatred and delusion – in other words, when you see such actions coming from imperfect human beings – should we be surprised? We should be surprised if people don’t live in this way!
According to Buddhism we are living in a crazy world. In that sense we are all crazy. Only when we are enlightened do we become completely sane. Why do I say we are crazy? Because we have created a subjective world and we live in this subjective world which does not correspond to reality. Who can say here that you always see things just as they are? The problem with us is we take this crazy world too seriously. So when we see crazy behaviour please don’t be surprised.
