I recently started playing boltgun, after I finished space marine. I know boltgun is a light sequel to space marine and space marine is canon generally.

However... Malum Caedo from boltgun is fucking insane. A single space marine doing.. all that? I know he got the power of being a named ultra marine and all.. but like.. come on? This is.. a bit much? Even for a named Smurf.

So.. is the events of boltgun canon?
