When you make up your mind and say 'For all the right reasons' or 'For all the wrong reasons', what do those reasons mean?

What are they referring to?
Like, are you willing to abandon all logic and just do it anyway? Or are you doing it cause you feel it's what's right even if something feels wrong? Like, when someone uses those exact phrases when making a choice, do they feel forced to make the choice? On what argument? Right/wrong reasons according to who exactly?
