First and foremost thing; currently at those time you are discussing allegations. The facts are not publicly available, and what is available is incomplete.

Second you are talking about entertainment media. The show is nothing but artistic storytelling for consumption of adult, mature audiences.

I’d wager you are very much projecting insecurities into the media that’s a reflection of yourself.

Stories that contain depictions of taboo behavior do not make deviants in & of themselves. Rick & Morty tells a superfluous & improsperous tale of a broken, dangerous, self depreciating family. Their story is not one of overwhelming success & happiness. They’ve destroyed their own lives, killed their family & friends; destroyed their home, neighborhood, town, world, solar system, galaxy multiple times over. It’s a story of sadness, loss, self depreciation, self harm, addiction, substance abuse, poor impulse control, moral failings & consequence. The inter-dimensional theme only acts a plot device to reset the stage whenever the characters ruin their lives yet again, but reinforces the concept that their behaviors are neither healthy or good. That their behaviors always lead to destruction, conflict & turmoil. It’s told with humor, as sugar helps a bitterant more tolerable.

Is Rick & Morty an idealistic show with healthy normative themes fit for the consumption of anyone? NO! But it’s certainly unfair to equate its production staff & fanbase as being sick in the head. Just because some media makes you uncomfortable doesn’t mean it’s promoting and glorifying unhealthy themes. If Rick & Morty seems to be influential, I think many themes are being missed.
