I will tell you what happened during this course of action.
I was gathering vehicle ammo crates in the Altis Liberation Arma 3 server with a Ch-49 Mohawk. However, I crashed-landed it by breaking the rotors on a tree, 3 feet above ground. I respawned at a HEMTT Medical that was not in practical use, however a player named PLAYER 2 was shooting the tires when I arrived. I told him to stop. He consequently shot me. I respawned, repaired the truck and drove off. He began shootign at the HEMTT with a Titan MPRL, but missed. I got back to my crashed CH-49, and repaired it. Another player, [Agente]Extremus5, got in the copilot's seat and started the engines. I got in the pilot seat, and locked the controls. As I was telling him to get out, as I wasnt taking him anywhere. He didnt and replied with a "fuck you". I got out of the heli to shoot the tail rotor (so he couldn't steal it). He then presumed to shoot me, and steal the heli, only to crash it in the nearest mountain.
PLAYER 2 was griefing and teamkilling.
[Agente]Extremus5 was also griefing, teamkilling and stealing stuff.
(For the record, they both had a score below zero before this all happened, meaning they teamkilling before meeting me).
