There's been a lot of talk about various aspects of Space Marines on these threads, and a lot of these keep coming back to different interpretations of how marines think.
So...what's YOUR take on Space Marine psychology? How do you see the mind of a marine working? Are they basically normal men (but a bit bigger) or are they fundamentally different to the rest of humanity?
To what extent does the total absence of fear affect other aspects of a Marine's mind? How do their various implants and enhancements change their thought processes? What about their environment and training? What about their experiences - constant war, bloodshed, violence etc...how would this affect them, mentally? Are they immune to ennui and mental trauma? What about their long lifespan-how does this affect their outlook on life?
Any thoughts?
