What's the point of this life in Christianity?

[Esquilax]

The problem is that, whether someone is considered good or evil, isn't up to individuals to decide. I think it's both a sort of concept, as well as attached to actions. Someone can do something that they think is the right thing to do, and not lose a wink of sleep at night, while another person can look on in horror and call for the first person's head.

Kudos for the Red Dwarf line, for sure, but we do have an objective measure by which we can ascertain the morality of an action, irrespective of the opinions of others; the reality around us doesn't change. The benefits/harm of any given action can be assessed objectively.
