Who has the saddest past? (EXPECT MANGA SPOLERS! ANIME WATCHERS BEWARE!)

[Carnage]

Who do you think out of the 8 members has the most depressing past? This my list:

1. Robin - became a fugitive at age 8. What can I say? She watched her Island and everyone close to her die.

2. Chopper - was hated as a monster by both fellow rein deer and humans when he was really young. He was even shot! He also had to watch Dr. Hiluluk die, and he was the only one who cared for him

4. Nami - Let me see here (I have a long list for her): Became orphan when she was a baby, then is adopted into a poor family (which really isnt too sad) but has to watch her mother be killed right infront of her face and must work for Arlong at age, what was it, ten?

3. Franky - His parents aborted him and so he was adopted. Then he watches his adopter die as he was framed. Harsh.

5. Sanji - Kid starved. Nuff said.

6. Zoro - Doesnt really become too sad at this point. His best friend died and so he makes a vow.

7. Usopp - Dad left him and mom dies of sickness

8. Luffy - Was there even anything for luffy?let me see.....shanks lost his arm?

Edit: Okay, Okay, I know. I suck at spelling ....
