I don't think Oda hates Kid, and if I'm being honest I think him getting obliterated by Shanks was fine for the narrative- it shows how much higher the story's stakes were getting and also showcased Shanks' power after a thousand chapters of very little onscreen feats. And it's super obvious that Kid will make a comeback.
The issue is with the agenda-driven fanbase who won't stop yapping about how much they hate Kid smdh
