Every single space marine dies violently at some point.

Either they're killed in combat, their ship is lost in the warp, their drop pod or thunderhawk is shot down, or they simply die in an accident (absolutely happens).

Most marines never make it to 1 century of service. To become a recognized veteran as a space marine is a true accomplishment, and a non-trivial amount of luck.

The fact that they're willing to kill off named guys is something to be appreciated, not lamented.

There is no retiring as a marine, even for those that end up training new recruits or taking care of the archives in the fortress monastary. They all die horrifically violent deaths eventually, and usually sooner rather than later.
