I understand he 'liked' his brother. But he has a real bad penchant for murking those that did him wrong, case in killing his blood father/brother. Its simply not justifiable enough to say, he likes his brother.
Agree on father. Disagree on brother.
Father was just a retard without foresight. Brother was an actual traitor. What happens to Doflamingo if caught? Life sentence in level 6 or execution.
We know Doflamingo's loyalty and love to his "family" is genuine due to multiple stuff that happened in the manga. Like for one instance, he risked his position by attacking Marines to get two of his fodder members free. He didn't care that they failed. Failure isn't an issue for him, treachery is.
People have their own freedoms, and Doffy could not in a million years convince Rosinante to sack his life for him
I worded it wrong.
What I meant was anyone in the main family would've been ok with being the one to eat Ope and do the surgery on him.
As saw with Vergo and Money, they would do it gladly even.
Point was that he simply assumed it's the case for his brother too, cause they all felt the same way.
