Hello, my suggestion is to make the character able to develop traits over time, because my character Morgan Freeman has killed almost 400 zombies and he gets very panicky after killing some(don't have the panicky trait), so I'm pretty sick of it because it decreases my vision. If it was an actual zombie apocalypse, I wouldn't be afraid of zombies after 1 month or more, so my suggestion is developing them over time. P.S. ...or at least make the character be less panicky after some time of surviving.
