That does not seem, to me, to be a smart move. For one thing, Aiden is known to have some ties to criminal elements. They're small-time, but that doesn't mean they couldn't do something to get revenge on Dylan, Sophia, and their whole family. Secondly, Aiden's Uncle is a top-tier lawyer and has thus made Aiden untouchable with regards to legal ramifications for his actions, so he could sue Liam and Sophia into the ground and take everything from them. Also, the cops can't touch Aiden because of his Uncle, which means that Dylan would likely be the one to face the harsh punishment for beating up Aiden. Finally, we don't know exactly how well-connected and influential Carl is in this city, so he might not be much help at all.
Overall though, Aiden does not seem like the kind of person that would give up so easily if he got handed a beatdown by Dylan. If anything, it could just make things far worse for him and Sophia. At the moment, I feel like the only one who could help would be Morello as it's possible that he knows Aiden's Uncle in some way, or maybe the Uncle is Morello's lawyer and he could pressure him to get Aiden to back off Sophia.
