For all that Daniel did, Betty and Armando did just as bad with all their actions. But since this is an ugly duckling story, only Betty is the tragic heroin who's redemtion seems worthy at the end. But I think both Betty and Armando were villains in this show.
The only reason Marcela hatd Betty because she was in the way of Marcela making sure Armando wouldn't keep cheating on her, trusting her useless best friend with the task neverless, but we can see Marcela hated anybody who was involved with Armando or helped Armando cheat on her, just cause Betty was ugly didn't mean Betty was the poor victim, she did her uglies to get hated by Marcela. Because anyone in this planet makes fun of ugly people behind their back. Marcela did it to her face once Betty started covering for Armando.
