Are people genuinely bad?

There is a dialogue in one of the Bollywood movies that “people are not bad but their time is” and maybe to some extent this is true. Sometimes people behave in a bad way when their life is a mayhem and they struggle to see good in anything as the issues they are facing are always at the surface but I have also met people and heard about people who are genuinely mean. I would accept the argument that it could be because of poor upbringing, bad social interactions and other exposures like that but it also depends on person to person on how much they absorb from their surroundings.

The worlds have seen geniuses emerging from difficult and worst conditions and also criminals emerging from the same conditions. What could be the reason behind this dissimilarities. I am not sure but maybe the absorption levels are a pre fixed programs into all humans.

Lets brain storm on this some more.
