What is your commen about BOM in Jakarta(Indonesia) yesterday?

I can never understand the minds of people who have totally disregard of human life. I am still unsure the real reason or motivation of all these attacks. But for whatever reason it may be, or whatever struggles there are for, or for whatever religious or political belief they are based on, killing innocent lives is totally unaccepted and must not be tolerated. Yet, how do we retalialte? Do we retaliate with equal force? Would it ever end? What does it take to end all these `meaningless' struggles? Or, humans are such that we are destined to destroy each other and ultimately brings about our own total destruction?
