Soul: Good to see your comments around here. My guess to your statement there:

1) At that point, it was too late and nothing much he can do about Vergo (and not forgetting Monet) at that time. Plus it was Vergo and Monet's own decision to sacrificing themselves for the sake of their young master (to blow away the island, taking with them Law, Strawhats and Marines to the afterlife). If I remember correctly, Doflamingo sounded grim and not exactly happy-toned when talking to those two for die for him. He is not one who openly express his softer side (in other words, crying or shedding tears) at such scene, too manly for that.

2) Remember he did IMMEDIATELY rush to PH to "save" Baby5 and Buffalo, that solidifies his caring for his crew.

I agree, Luffy will go all-out crying for Zoro if he died (reminiscence to his reaction when he lost all his crew to Kuma at SA) but I think Doflamingo's character was build around the manly idea that "a man does not shed tears but only blood" (a Cantonese saying).

N700 said something that gives me a point of thought, smiling and laughing may be his "defense" against everything weak of him. Kinda like Seta Sojiro of Rurouni Kenshin (Soul should know this). So even when he is sad (losing his old friend Vergo) he may do a sad face at the most, crying does not suit him unless he realizes he has lost EVERYTHING - power, friends, influences, all - that would be the point when he breaks mentally.
