If you accept that the "Dennis Eichhorn" character in these comics is a fictional alter ego, and that you're not supposed to like him, can you really infer that this is a true reflection of the real-world Dennis Eichhorn's attitude toward women and his overall self-concept?
It could be so, but it could also be that he's taking some real incidents and imagining what might have happened had his basest, most shameful instincts taken over -- the kind of base, shameful instincts we all have (unfettered greed, cowardice, self-preservation above all, vengefulness, etc.), but most of us never give free rein. In that light, it would simply be an exploration of a man's darkest thoughts, not a reflection of the kind of man he really is. In literature, this is common as dirt.
