I agree with Ayn Rand on this. Human are by nature neither evil, nor good. Humans are blank sheets; we equally have the capacity to manifest good and evil. It’s our choices and decisions that determine who and what we are. Being good leads to human flourishing, “goodness” is good exactly because of this reason. But you have to act upon it, don’t be a passive observer of life, live it to the best possible standards; you make your own life, you decide your own standards.
