Team killing, team provoking, and kicking

The other day I was playing halo 5’s arena mode, up until this last match I’d almost forgot that friendly fire isn’t active and you can shoot, distract, annoy, and kill other players. And I witnessed and luckily recorded the act of this player as he ruined our teams cooperation by some time shoulder charging into his own teammates well they were sniping, shooting them well they were getting shot by the enemy, just all round being a bully to our team. What he was doing was provoking us to fight back and kill him so he could get a chance to kick us for betraying him, which did happen to one of our players making our already loosing team one man/woman short.
now there wasn’t much I could do besides report this player. But I wanted to see if there could be something done to put friendly fire into multiplayer and make it impossible for team kills, it’s tough for me to kinda say this because it is a key feature of halo, well every other multiplayer game takes out that realistic aspect, in fact most just let you faze through your team making it hard for players to get caught in doorways like a car jam with players

I don’t know, I just want this issue to be heard and if there can be anything else I can do or we can do to help stop this behavior, and let me add by just making betrayal punishments harsher won’t fix anything because a lot of these players aggravate others to have them do the betraying thus punishing the innocent players.
