It's sad that you hear about suicide bombing happening almost every day in various parts of the world. To sacrifice oneself for some cause may be regarded by some as worthy or even noble, but if it involves killing other innocent people, even children, then it has to be misguided and wrong. God has clearly commanded us not to kill, so carrying out such attacks has to be a selfish act. (Abortion is in the same category.) By the way, if you terminate someone's life before that person has had a chance to repent before God, then you are also responsible for the possible loss of that soul!
