Once when seizing a city, one unit was standing (idle) on a corner of the fully captured walls.
One by one all the men of this unit started to throw themselves off the wall into a horrible and pointless death.

I decided to not to interrupt them and see how many would survive these self-destructing spasms.
The entire unit got wiped out.
Didn’t felt the least bit bad about it cause I don’t wont morons like that in my army.

I think they where principes.
