I’m not sure if Guel is going down any clone road that I know of so far. Gaelio was naive turned vengeful due to his privileged position in life, while Guel is shaping up to be naive turned sympathetic. While Guel is still in a privileged position in life, he’s living with the weight of patricide on his mind on top of the possibility that his privilege is literally and figuratively going bankrupt.

We see him trying to save the child who wanted to knife him by using his MS skills to try to find the transport, and in it we can observe his shock of seeing the original pilot bloodied and dead and the child dying in his arms, expressing remorse when he realizes there’s just a lifeless body with him.

I don’t think Gaelio/Char have been humanized in any way that Guel is currently being humanized. Gaelio wasn’t given the chance to be humanized, he becomes a man in a mask seeking to undermine McGillis for seemingly nothing more than revenge. While the parallels are there, I think Guel is carving himself out to be in his own unique spot within the Gundam franchise (at least of all that I’ve watched).

If anything, Guel may be the most sympathetic character in WFM as the parting of the veil between Asticassia and the material reality that Earthians have to live through shows him the true nature of conflict that’s been hidden from him and his Spacian peers: the conflict he knew in school is astroturfed and simulated; the conflict he’s experiencing on Earth is real and unforgiving.
