Right and wrong aren't that hard to see in a narrative.
If you mean that the moral polarity of good and evil espoused by a work of fiction is usually pretty straightforward to derive from the text, fair enough in many cases; if you want to argue good and evil as being self-evident, I'll part ways with you there. (Harry Dresden and Mr. Spock are both generally taken to be heroes, but they have radically different positions on the notion of the greatest good of the greatest number, for example.) It may well be a consequence of growing up in an environment where both my perceived politics/ethnicity and my perceived sexuality were things which some people around me were willing to be very negative on based on their zealously held takes on good and evil, up to and including risk of serious violence, but if you give me a text that suggests good and evil are obvious to all right-thinking people, I will find it untrustworthy and repellent.
And the point of fiction is to escape like the point of candy is to taste good. If those things make you feel guilty you might want to look at why. Neither of those things is wrong when it doesn't hinder your ability to manage life.
I'm with Professor Tolkien when he said that the word for people who object to escapism is jailers, but I'm rejecting the notion of a black-and-white setting where good and evil are clearly laid out as one there's any appeal for me in escaping to; in that kind of setting, I always feel I'd be one of the people hanging from a lamp-post for not buying into the relevant notion of good.
I'd much rather escape to a rich and complicated banquet with lots of different and interesting food than to a heaped pile of refined sugar.
Enjoy life. It isn't incredibly long and most of it isn't fun.
If that's the case for you, you have my sympathies. I've been able to get to a point where rather a lot of mine is, and not by doing anything that seems impossibly difficult for many other people to do.
Besides which, everybody could use some good old fashioned heroic altruism beat into their brains.
Applying a statement like that to people who have no self-confidence already and who are full of self-loathing because of constantly being held to impossible standards, for example, is a fairly straightforward way for a simple take on good to generate suffering as a byproduct in ways that work for me as evil. That's not one I intend to write much about myself, because I'm rather too close to it personally, but it's a useful source of conflict in a story somewhat more sophisticated than merely light versus dark.
