Forced to choose between his precious tower, or ANYTHING else, I think its quite obvious what his choice would be. This is callous. He would not find happiness in ANYTHING but acheiving his goal. This is anhedonic. And he would do it without grimace or tears. This is emotionless. I dont hate the guy. He is what he is. I just enjoyed the glimpse of Roland's vulnerable side that we get to see in W and G.
