Keycard Room Duality

Dam Battlegrounds, Hurricane, Dam Staff Room.

1st game: I run to it, see it has been opened, tried making my way past since I didn't think there was anything left anymore, suddenly a jolt mine pops out and a guy comes out the room to kill me. He didn't even knock me out, just shot me until I was downed. A bit more context, I am a friendly raider, meaning this guy had to have been friendly (or at least oftentimes) to be in the same game as me. That wasn't even the extent of his paranoia because a few seconds later, I heard a stun grenade go off as a was crawling away but no shots. He really stopped looting and opened the door to throw a nade lol.

2nd game: I tried going again but I see a guy go in just as I arrive. Was about to just leave when I heard a shredder get in and blast him. He barely gets out and starts healing. I was just outside waiting because I was curious. He held his weapon but didn't fire at me. I was gonna go on and mind my business but decided to help. So I took out my gun, went by the door button, and repeatedly toggled my flashlight. He understands and so I open the door and we shoot it down. He thanks me and I just left and let him have the room.

It's just interesting to see the duality between people in this game, between the ones who are cautious enough about their keyroom being invaded that they plant mines and lob nades and those who don't see others as a threat and even form alliances. Which kind are you?
