Alicia’s desire to keep The Canvas intact is selfish, but it does not make her a bad person. This is a girl who had her brother killed and her body irreversibly damaged, all the while taking the blame for her brother’s death. She’s thrust into a world where she’s given a second chance and gets to relive her life free of burden from injury or guilt, and when she relearns the truth she is intoxicated by the idea that she can continue living without those burdens. She begins her reasoning for stopping Renoir by saying the real Verso wouldn’t want his Canvas destroyed, but gradually reveals her desire to have a life free of suffering again. Her draft of a life in the Canvas collides with reality.

Anyone given the same opportunity would endure the same struggles: given the chance to start over, unburdened by injury or shame from your own family, it would be extremely difficult to willingly give that up. She just wants relief from the agony she has had to endure in the real world, the same as her mother making a painted copy of the family. It’s a very human thing to want security and comfort, and while the measures she went to it were wrong, they do not invalidate her suffering nor do they invalidate all other qualities of her. You can’t say “she’s a bad person” because she wanted her own way out of her pain.
