That i think wise men are more likely to be kind？

Yes. They're generally more thoughtful than other men. It's wise to be kind, quite frankly.

Yeah; however, wise men and women know when a situation requires kindness or assertiveness, and can be kind without being gullible.

Being wise, doesn't always assure kindness.

A wise man quickly recognizes situations where kindness engenders a positive outcome. He also recognizes situations where a mean spirit will preempt trouble.

Who would ever profit from giving kindness to charli.m?

Anyone here ever seen House of Cards (I'm aware the protagonist is a fictional character, but it makes the point nonetheless). Frank Underwood is quite wise and Machiavellian, but he's certainly not nice.
Just like everyone else, some wise men are nice, some are mean.

Wise men rarely have patience for stupid people.
