TTT Weapon Help

Hello. I have a traitor weapon that I did not create. My server loves it but it affects the karma imensely. It’s called the Brain Parasite. A traitor can use it on an inno or a detec and it causes them to start shooting uncontrollably and when they either hit someone or kill them it brings down their karma.

Now, the karma can be fixed but is there a possible way to make it so that if they kill someone, the kill will be directed to the Traitor? That way it could be that Karma isn’t lost and RDM’s wont happen.
