It is an interesting debate; both sides have a point.
Andres raises a kid he knows that's not his own, regardless of the reason that's yooge. Was it for selfish reasons? Perhaps at first, he did it to leverage Emily's feelings, but once she broke up with him, he still did it. For five years, he did so without Emily's input, and if not for Emily blurting out that he's not the father in desperation (more on that later), he probably still would be. Yes, he turns out to be a womanizer, but we have no proof that he wasn't a womanizer with Emily. The only reason he got caught cheating on Haley was that MC had seen him. But that has little to do with this debate other than it turns MC off from him, so we'll move on.
When Santi is told he has a kid, he doesn't react in the best way. He likely has his parents pressuring him to drop her off, and when he goes to see her, she rejects him and disappears. He randomly runs into her and learns about the kid but still has to stay away from him because that's not his kid any more. So he watches from afar and interacts with him when he can, but he's not forcing the relationship. Could he have fought harder for his kid? Sure, but he also had parents pressuring him and his future in danger. I'm not saying what he did was right, but from a character standpoint, I get it. He took the path of least resistance, which I could see why that pisses people off.
Which leads us to Emily. She's living out her wild college days and gets knocked up. Emily is probably not ready to be a mom yet, but she knuckles up and settles down. She tells Santi, and he doesn't react in the best way. Then Santi's parents try to force her into an abortion, so she decides, for the sake of her child, to go with the dependable guy, but also a guy she doesn't love. She stays in this loveless marriage until she likely accidentally breaks one of his conditions by meeting the child's father in a chance meeting. Then they break up. By this point, everything is fine; her child has a father, and they're successfully co-parenting; then, she loses her child for five years because of something that has nothing to do with her. He finally returns and catches her with Melissa; seeing that he's angry and she'll likely lose him again, she desperately reveals the truth about his father to stop him from running away again. Was that selfish? Sure, but what choice did she have at that point? Ultimately, sure, she could've been more careful if she was living out her wild college days, but when push came to shove, she stepped up.
They all did regrettable things, but nobody is the bad guy. That being said, I could see an argument being made against all three if one wanted to do so.
