O come on!!!! This love and all - is a feeling and i know it hurts and all.. but cant kill anybody. We human beings are very mean creatures. We have been doing crazy things to save our lives, on the cost of other people's lives. History of mankind is full of such examples.

To sum it up, we let our hearts entertain us for as long as possible but when it comes to living or die thing, our brain kicks in and it shuts down all feelings.
