Just my opinion but i wasnt looking at the aim hack because i couldnt see anything weird but something did spring up on the first demo where i'd often use the expression ''he knows''
Lemme elaborate, the guy is very clearly a good player who uses sound but there was two bits of evidence that can seperate this. A good player who attacks the same position twice in a row will often use the same tactics on how they attack it and he's very clearly 'dodging' peoples lines of sights in the video. He waits for too long out of sight ''listening'' when in matter of facts the guys just moved behind the box or away from the doors on long.
also, in the second video when he's in tunnels and he crosses over and theguys at t spawn. IF you watch carefully, he turns away and destiny runs across but the guy at ts base turns back .
I therfor think the guys a wallhacker not an aimer.
I believe embrace might have a few things to say as they're both friends.
