好歹 (hǎo dǎi): ดีและไม่ดี

He is your father, good or bad, and you should respect him.

Regardless of whether it's good or bad, you should at least give it a try.

At least eat something, otherwise you'll starve.

He is a manager after all, so he should be careful with his words.

Things always have their good and bad sides; we can't be blindly optimistic.
