I was watching him and it doesn't seem that he was dying on purpose, also he wasn't killed by these 2 only, pudge got him a lot aswell. I also checked his other games at that day and he only played with 1 of these 2 but he definitely didn't feed then. Maybe for some it wasn't obvious that he was ruining the game so they didn't agree to kick him, that doesn't make them his friends.
But still, he didn't put obs until min 30 while carrying them (7 obs in inventory), especially the ones luna bought. Later he typed !ff and stood in base while you were taking mid trying to comeback (at 44 min until the end).
