essentially space marines are effectively daemons that can be deployed in the materium
Thats it. Its made more apparent by the nature of the berzerker, which is basically a animal deployed in the bulk of enemy forces to then let loose an unending desire to shed blood, rage, and etcetera until they die or finish objective and is then recaptured to be put into containment until the next location of battle
basically eversors but not a temporary use field operative that then goes into stasis for whatever number of years. Space marines can effectively be deployed continuously nonstop and they can and are known to be capable of exterminating entire planets
that being said space marines are still a piece of military equipment. Forces like the imperial guard are the backbone of an empire and space marines are a tool that are deployed where they are most useful.
