Can U Date A Girl/guy Who's Got Halitosis?

My dear friends this is just a simple one. for the ignorant-halitosis is the medical name for (badbreath,foul mouth..etc).
my friends sister is suffering from this condition and ma heart bleeds for her cause she's very pretty.*pretty doesn't just go well with badbreath,does it?*yuck!
I  would very much date a halitosis-less her....but with such condition? HELL NO!!!!.Can you?
