Despising it is good. We hate it just as much or even more. Many people crave for immortality, but we who have something close to it would give it all away just to be able to have that one live normal people have. Even if it's filled with battles and suffering. At least then we could choose the way we died and it would remain a sacrifice rather than a "see you later" while everyone else gets to sacrifice themselves.

[He grunts to himself, frustration spilling as much as his anger for the situation. He didn't ask for this, no one told him, no one knew, that being the Phoenix Saint involved so much of being a phoenix. Everyone thought it was a title, a cloth. Did Marco ask for it? Did he eat the devil fruit because he wanted the power it would give him? Whatever power it could have been, or did he know what it meant? Did he underestimate what being a phoenix meant? Did he eat it by accident? It doesn't really matter, nothing changes that.]

Shouganai. There aren't many expressions that I can hate more than that one. But unless Marco stops being a phoenix, there's really no way around it.

I don't suppose he ever told you how he ended being a phoenix, right? Besides the obvious "ate a devil fruit" part.
