Negativity bias (from wikipedia: "Psychological phenomenon by which humans have a greater recall of unpleasant memories compared with positive memories"), or some other modification reducing negativity in my perception of the world for myself.

Maybe toning down scope insensitivity for the whole human race? (I'm not sure if completely eliminating it is a good idea - I don't know if having a brain which feels the correct emotions about arbitrary amounts of suffering would be too traumatic and lead to paralysis. Whatever level of modification that leads to correct actions)
