I believe there are absolutes.

Like gravity, time and space.

But, you say, “What if there’s another dimension outside of our awareness, where these rules don’t apply?” Then that dimension would be governed by its own absolutes.

Within nature, there is a hierarchy  But, among humans there is not.  All men are created equal.

But, you say, “I’m not good at math, and Henry is, so clearly we are not created equal.”  However, you do have equal value in God’s eyes.

So, you may kill innocent bugs, but not innocent humans.

But, you say, “A noble war may have innocent casualties.”  In this case, I believe it comes down to intention. Did you intend to kill innocent people, or not?

But, you say, “Innocence is subjective to perspective.”

If your endgame violates our fundamental rights as humans, then that is absolutely wrong.
