Cover art for Good Day To Die lyrics by Godsmack

Could someone explain me some words?

"Who really knows what rights all the wrongs anyway" What does it mean? Does he ask: what does right all the wrongs? Or he means by this - Rights are all the wrongs. "what" means "that" or not?

"With all I know" What does he mean by "all"? Everyone or everything he knows? He says goodbye to everyone he knows or "It's time to say goodbye with everything I know"?
