Some people care about relationships and others don’t. Our own character is the basis of how we relate to other people.
We wouldn’t expect “fools” to make many good personal choices or do well in relating with others – they will “mock at making amends for sin.” That’s because fools simply think they have it all figured out and are going to do what they want to do (see Psalms 14:1).
Consequently, they don’t really care about others – except how they might be able to take advantage of them. Others are just collateral damage in a fool’s quest to do what they want.
On the other hand, “the upright” – by virtue of who they are – do care about others and will make good choices. They know “goodwill” toward others is a right thing to do, but they also want to practice it in their daily interactions.
In the end, how I treat or deal with you is about me and my attitudes – not about you or your actions. I can treat you appropriately and you can’t stop me!
