He's not emotionally strong enough. lol& was so traumatized by his wife dying that he's the only person besides Angela that resonated with the Library. Angela's one million years of psychological torture in Lobotomy Corporation is the only thing comparable to how deeply Angelica's death fucked up Roland.
If Roland did get EGO there's a good chance it would be a Dongrang situation where he would turn into a worse person.
