“That makes no sense. No sense at all. Why would they do that?”
If you believe the universe is nothing but a bunch of particles randomly slamming into one another on the long path to eventual heat death of the universe, then curiosity isn’t valuable, because there is no meaning behind what you observe.
That’s not my worldview. The instinctive drive to create a story out of what we observe tells me that no one has a purely material worldview by default.
When you see something crazy, odd, strange, and (to you) senseless, remind yourself that people make decisions and behave in certain ways because it’s logical or rational to them. Even if it’s just the least problematic way to live. No one is consciously irrational.
There is a Why in there somewhere. There are usually multiple reasons. There is “schtuff” below the visible waterline. There is history.
Dig deep for these when you need to understand why something is the way it is.
