ALSO, space Marines don't have huge screw ups. they're all given hypo indoctrination during training, and that'll smooth out a lot of the... rougher edges of a recruit.
Just a note about the hypno-indoctrination, as the Deathwatch novel goes into some detail regarding Deathwatch training and integration. One of the key traits of a marine to be selected for the Deathwatch is a willingness to be open to the differences of other chapters. Hypno-indoctrination helps but it requires the right marine personality for it to keep. There's both positive and negative reinforcement used. Marines are instilled with recordings of famous victories from the chapters of their squad mates. They see how well they can fight when they're at their best. However, a marine who acts up, such as a Minotaur in the novel, is forced to endure recordings of some of the worst failures from their own chapters, watching their own brothers being slaughtered and essentially using the chapter's own hypno-indoctrination against the marine as a form of punishment. Looming over all of this is the fear of being sent back home, dishonorably discharged from the Deathwatch due to inability to cooperate. A fate many marines would consider worse than death.
