Hate is a virus.

When we notice that others ignore norms and follow impulses, we easily allow ourselves to succumb to whatever impulses we have. That is, whenever we grasp hatred, our own self-control declines. A famous person donates money for hot lunches for doctors - "he's a bastard - it's nothing more than PR." A famous actress sets up a fund to help sick children - "well, it's definitely a corrupt scheme." Even the worst of times pass. But the anger in our hearts will accumulate and grow until it ruins all the good in each of us. Remember, the one you hate may not even know of your existence, but the virus of hate can start certain negative psychosomatic processes in your body.
