"La imposición de crueldad con una buena conciencia es un deleite para los moralistas. Por eso inventaron el Infierno."

Simplified Meaning:

People who consider themselves very moral or righteous often feel they have the right to judge others harshly and punish them. This makes them feel powerful and right, even if what they are doing is actually quite cruel. For example, in history, there were times when religious leaders said certain people were evil and must be punished severely, believing they were doing the right thing. This led to terrible acts done in the name of morality, like inquisitions or witch hunts. In everyday life, you might see someone being overly harsh to someone else because they believe the other person deserves it, which makes the punisher feel justified and good about themselves. Understanding this can help us be more compassionate and less judgmental, realizing that being too harsh, even with good intentions, can cause harm. Instead of focusing on punishment, it’s often better to try to understand others and approach them with kindness, even when we think they’ve done something wrong.
