In the film avengers: infinity war the main villain, thanos, wipes out half of the life in the universe. his rational for doing this is that without some sort of intervention all life would cease to exist. and, furthermore, that those left behind after he destroys/unmakes will see a more prosperous and peaceful life. was thanos right/justified in his actions? why or why not?

Explanation:

His conclusion is correct. We are overpopulated. Our planet cannot stand double the population it currently has. Waste for one thing is an unsolvable problem with 14 billion people on the planet. We are already in massive trouble with 7 billion.

But the moral principle involved is not correct. Laws have been set up that prevents us from killing each other off. Holocausts have solved nothing but that we are capable of mass murder. The population problem and all it's side effects have not been eradicated.

The Bible records God's attempt at doing what Thanos wanted to do. He saw immediately after the flood that was not the answer. Too many people is one thing. Murdering half is no answer that will work.
