Morality is about doing the right thing, not finding the best way to do the wrong thing. This may sound obvious, but the behavior of the world shows otherwise. People support and vote for cruel things. They might recite a humanitarian quote, and then go against the humanitarian agenda. It’s what some do every Sunday in church, while simultaneously voting to deport and kill people.
When reading something about morality and ethics, don’t just read the words and move on. Think about them. These philosophies are shortcuts to understanding large concepts. Simple sayings and aphorisms should make you think, and if you disagree with them, they should make you write (or express your critical thinking in some other productive way). Think about your principles in depth. You may find you don’t agree with yourself on some matters.
There are two things people never forget; cruelty and compassion. Considering our own interest, which would we rather be remembered for?
