There are party loyalists out there. Unfortunately, they constitute the majority of population and they vote and decide who governs you. Can't neglect these unconscious/unaware populace.

The question was about behavior. Imagine if there are 4 children - Voting Blue kills 2 children and voting Red kills 3 children. By voting Blue - we've saved 1 child and start celebrating. The problem here is the behavior of cheering such leadership, by cheering we're burying the core problem of "Child killing" and erasing the acknowledgement of "No child should be killed" ideal from the mind of the masses.
