Ellie makes it pretty clear the path she would have chose. Joel violated that not for her benefit but for his. That's why he lied to her because he knew what he did went against what she would have wanted. Joel was a dirtbag. Walks in that facility and kills all those people just because he didn't wanna let go and move on from the same girl he chewed out and tried to dump off on his brother.I wouldn't have let them take Ellie either. Hoe ass Marlene wouldn't even let Joel say goodbye to her. She got what she deserved
