I just finished and got the nurture ending but oh my god this is one of those games that's going to stick with and haunt me for decades. The slow build up of the characters from seeing them as their archtypes (an 'innocent' driver and the hiker who murders him) to finding out how complex they are and what kind of story they have to tell was amazing!! It's one of those games I wish I could play for the first time all over again and it's truly underrated <3
