Others can be subjective good. Or subjective evil! Or mostly-objective good or mostly-objective evil!
In fact, egoism, or altruism, I have no idea. Neither do I think it's
ethical to assign morality to others based on my ideas of what they
are.
Simply, it leads to huge confusion.
Even sexual predators like Jeffery Epstein. take advantage of this to
guilt-trip victims. Pleasuring them, while doing harm at the same
time?
Again, there are philosophies that assume the world is good, and there
are also some that assume people are self-centered and use others as a
means to their end. However, few actually see it as a mix within the
world, while there are corrupt politicians, there are also good
politicians. So as most people don’t believe and can’t alternate at
multiple things at once, most simply get confused and act in strange
ways in real life, either feeling betrayed when someone does a bad thing
even though it’s not their fault, or the converse of feeling in a daze
when someone does something good for them.
