Let’s just say that when they praised Samson for killing thousands with the jawbone of a donkey, he said, “I did whaaaaaaat??”
I heard sin described as when you take something that is good and make it good for nothing. I think that applies here.
No, Samson was a Nazarite. He had taken a specific vow to eschew to avoid anything from grapes. That included wine (and raisins), etc.
