My pawn/Ben just killed 4 of my colonist's

So my level 20 construction pawn named Ben had a pretty bad day, not sure why he had a bad day, unlike his friends, he didn't lose his wife, anyways Ben went into murderous rage and he wanted to kill my very important colonist "Wood". The reason for that anger was starvation, Ben decided not to eat and was mad.

Ben entered Woodys home while my 2 other pawns were running over to stop him, a fight happend between Ben and Woody but guards arrived in time and were attacking ben from behind.

Woodys head fell on the floor, after that Ben turned on Colonist-1 and downed him, 3 hours to die

He then turned on colonist-2 hit him in the lungs but before he could finish the job, colonist-2 cut off Bens head, all 4 colonists that were involved had died, 2 lost their heads, 2 bled out in the end, from 8 colonists I was down to 4, this also happend after a raid where I lost 2 other colonists

In 10 minutes I was at 4 colonists

2 hours later I'm at 12 Colonists now, my colony got carried by a single pawn who did all the cooking, all the crafting, all the growing, all the medical. She ended up dying to maleria because flashstorm wiped out all my healroot, she is the only one that isn't burried in a grave.

Btw it's medival playthrough
