I watched Scarface last night and I am now conviced that he did love her or was just crazy about her. because he did not want any one with her. knowing that she is going to do what ever she wanted he should have been happy that she was with Manny at least he would of know the person she was with. Because even at the end he feels bad for killing Manny. so yeah in the end he to me was in love with his sister..
