Regardless of your politics, stop and think for a minute. This man was, assuming what he writes is true, personally responsible for killing 93 people, none of whom had any chance to fight back, prepare themselves or do anything at all. This is a step or two above cold-blooded murder, but not far. If you had spent several years doing something like this, why would you write a book about it? Why would you glory in it? A best-case analysis is that he felt this was something that had to be done, distasteful as it was. Then do it and out of respect for the people whose lives you had to end, shut up about it. But presenting this horrible career in slaughter as some kind of role model or heroism is obscene. What kind of mind would view it that way? This whole idea is sickening.
