He had so much time to react to his radar, it is 100% his fault that he died. There are spawn issues but take some damn responsibility for your surroundings!
The thing is you can say, "it's his fault he died" but that still doesn't change that fact that he got a terrible spawn, now does it? He could have killed the guy with the shotgun and it would have still been a terrible spawn.
Getting the kill or getting killed doesn't change the fact that he got spawned right next to someone and that should never happen.
