"He's right, but he's a gigantic ass" pretty much sums up Kaibara's character. It does make things more dramatic (which is fun for me, as his translator), but he's definitely not someone you'd want to emulate.
Honestly, he tends to remind me of Gordon Ramsay a lot, and the toxic kitchen culture he's helped popularize. I don't think Kariya did that on purpose though, he's clearly drawn direct inspiration from Rosanjin, who is similarly temperamental.
