Avengers End Game - Petulant Retaliation

This post was of course set off as the title suggests by the movie Avengers - End Game.

I know that so many people loved the movie. As a cinematic experience, i liked the movie, however i completely disagree with the morality of the story if you will.

Here are the reasons why?

• How is it Ok for Iron Man to snap his fingers and wipe out Thanos's army?
• Don't they deserve to live like all the other beings that were brought to life?
• Did they all have the same principles as of Thanos - that to wipe out half the life of the universe?
• What about their family and friends? - Don't they deserve time with them?
• Its been five years since half the life was wiped away.
• If they are brought back suddenly and the rest have lived for 5 years.
• What about the emotional and psychological effect on all the sentient life forms?
• Did the heroes think about that?
• How are the life forms gonna cope?
• Both the life forms that survived for 5 years and have adjusted.
• The ppl who have returned. 
• What about the availability of resources for the people who are returned.
• So, the heroes would rather that many life forms live in poverty and disease, compete for diminishing resources rather than with plentiful resources for all?
• I mean Thanos makes it very clear why he is doing it. He is not trying to become a tyrant (Sure he presumes to make the decision for all of life, but at least his logic for what he is doing is clear and understandable). He wants to see life bloom in its full magnificence. 

In short, the only reason i think the Avengers do the snap and return life is because of petulant retaliation. It's because Thanos defeated and bested them. They just want to be the winner, no matter the cost. 

And oh yeah, if I were to get a gauntlet like Thanos - I would do the same thing he did.
