I think I will blow up the bomb on the bus.
Why do you want to detonate a bomb on the bus?
Because of the people on the bus.
It is wrong to harm other people. Thus you should not detonate a bomb on the bus because it will cause great damage and bloodshed.
I don't think something like that will happen, you are being really negative.
What else would a bomb do that explodes next to a bunch of people? Harming other people is a real crime. If you are there too you most likely will also die.
