If the non-Catholic is not baptized, the non-Catholic has original sin and is damned, "unless before the end of life the same have been added to the flock," as Pope Eugene IV puts it in his Cantate Domino.
If the non-Catholic is baptized, he does not have original sin, but he can certainly commit actual sins (mortal or venial).
