After watching the video what I’ve noticed is that he knocked you with he shotgun (while your hp was decreasing because of his mol) and the other guy took his kill so at this point we can’t say that it was intentional death evade and also he do not have any history of d-e, On the other hand what you said is right he was using the mols on low hp which can increase the risk of d-e. So i’ve decided to give him a verbal warn this time for using mols while having low hp. Solved.
