Why do rats always cuss you out after you take them out?

Setting: Pilgrim's peak cold snap.

A few notes:

1. Ignore the part where I accidentally set myself on fire lol... I meant to heal but the real life adrenaline was pumpin so I misclicked onto the fireball burner.

2. tbh I wasn't 100% sure that I got the right guy initially. I was out for blood and basically shot at the first person I saw. Been ratted too many times now so it's shoot first, ask questions later. But good thing he cussed me out so that I could match his displayed name with the post-match summary.

3. Right before my second encounter with him, I think he may have been ratting another player? There seemed to be another raider that went down to my right after I opened the door.

4. I probably scared the bejeesus out of the 2 good dudes around me with my paranoia haha... I thought the guy that was defibbed might have been the rat but good thing I didn't shoot him.
