It seems to me that Thailog has an obvious complex with his 'father' Goliath (perhaps with all three of his fathers actually) but in particular I think that in creating the first set of clones he was trying to build something equal to what his 'father' had, with Demona's influence of course.
Clearly after the comics Thailog will continue cloning to try and build his own clan, but I wonder, should that clan fail too, do you see Thailog, no matter how successful he is in business and his other ventures, always trying to compete with Goliath on that personal level, and seeking a clan of his own?
I don't know how to answer this without at least implying spoilers, which I won't do. And in any case, this feels like the kind of thing best left to each fan's personal interpretation.
