I hate to say this, but this kind of Ditko has always made me think of "What if Jack Chick were an atheist?"
The main problem with Ditko, and Objectivism(and this is coming from someone who in high school was part of the cult, so I'm more critical perhaps than most of it), is that it mistakes its strawman principles for exact reality. It's one thing to say it as an allegory. But when reading this I get the feeling that when Ditko looks at the world this is what he actually sees, just like this.
It's also one thing to say one should have the CHOICE to help others. Fine. But some objectivists take this as an excuse to NEVER help others, as a matter of principle in itself. It's not that you should never help others, it's that you should have the freedom to choose. But many just use it as a justification for their own lack of any empathy for others and think the act of freedom is in the refusal, not the consideration of the question. This is where it becomes a philosophy of sociopathy.
Rand was never helpful on this as she always looked at it from the negative angle. I remember the essay in VIRTUE OF SELFISHNESS that started my own break with her. It had to do with the question of whether you should save a drowning man if it puts yourself at risk. She did not even address the question(because, I don't think she could) but rather spent pages avoiding the question as not worth considering in the first place. That, to me, was cowardice.
Also, I believe that Objectivism nearly always, if taken to Ditko's(or even Rand's--if you've read THE ROMANTIC MANIFESTO, and I do not recommend it) level, nearly always results in bad art. It has a way of turning it into nothing but more regurgitation of Objectivist talking points, and artists into missionaries. And no, the "hero" is not the only worthy subject of art, and art is not always meant as a moral example, a type of thinking that only can lead to stiff, useless propaganda. Those principles are the same as those that inform socialist realism, an irony also not lost on me back then.
