I wasn't implying anything about Sanji's personality. I was pointing out similarities between the arcs. With that said, there are some backstory elements that I think are worth pointing out.

1. Both Sasuke and Sanji come from infamous families

2. Both had a strong a strong familial presence in their lives until about the age of 8

3. Both have an older sibling with whom they share a particularly complex relationship, and who facilitated their break from their family.

4. Sasuke's and Sanji's motives for defecting are pretty much opposite. Sasuke cut his ties in order to gain power to avenge his beloved family. Sanji reluctantly left his friends and returned to the family he hated in order to protect his friends.
