First of all, can you please start placing dots? It would make it easier to read.
Second of all, I think it's rather clear that Dofla does care about his crew, even tough somewhat twisted way! He may not be above sacrificing them when he really needs to but he doesn't do it with glee either! I think silversatyr's mafia comparison is the best: He's got strong bonds with his crew but if they betray or screw up big time, they have to pay for it!
Either way I'm still confused about Law's plan. Did he really just want to kill Doflamingo? Was the Kaido thing just a ruse for Straw Hats to feed? And if he did, why not just kill Caesar and let Kaidou take care of the rest? There's probably still something more than a mere revenge going on here. I really hope so, I was really waiting to see what Law had planned for Kaidou!
Killing Caeser is useless if the production facilities for SAD still exists. Hence he needs the Strawhats to destroy them.
There's also the possibility of Law only making it personal with Doflamingo to distract his thoughts (whereas if he really wanted to, I am sure that Doflamingo could go back to protect the SAD factory). I still think there's more to it than just revenge, with revenge of course being a big part of it. Why else would he care so much about protecting the Strawhats and stalling for time? Keep in mind it's Law… He can always get to safety whenever he pleases, unless he is being harmed by seastone. I think it's just another way of stalling for time.
