Tbh at this point, it's not the Left Eye that is bothering me, i'v already prepared a lot to explain it (Including how & why Zoro got his Scar)
But what puzzles me is why does Oda associate "Christian Cross/Jesus Symbolism" with Zoro a lot
1. He was introduced on a Cross
2. Mihawk, his End Goal is someone who carries The Cross
3. Kuma, the Only Shichibukai that had Memorable Experience with Zoro, carried The Bible
4. After Zoro fell on Mihawk's Island, he noticed Huge Tomb Cross
5. Yasuie who bonded with Zoro & was Highlight of his Sub-Adventure in Wano, was killed on a Cross
6. Also Yasuie Name if written in Arabic, refers to Jesus Christ
7. He was bandaged after Roof Fight in Cross Shape
8. Right after that, CP-0 represented Alliance on Shogi Table as a Christian Cross
