Am I crazy if I cancel a international first class award redemption to book business class?

Context is important here. My wife and I are visiting Japan in late May. I booked two business class flights on the JAL A350-900 from DFW to HND (we live in Texas). For the return flight, I was only able to find one JAL business class ticket on our preferred date which I immediately booked for my wife in business class again on JAL A350-900 from HND to DFW. I initially was unable to find any business class fare back to the US for me on our preferred date. However, I did find a lone first class ticket on JAL from HND to LAX, 2 days after my wife leaves Japan. In recent weeks, I’ve found and speculatively booked flights on STARLUX in business class from Tokyo to Taipei, and then TPE to LAX on the same date that my wife returns to the United States. Am I crazy if I cancel my JAL first class award redemption and go with STARLUX business class? I don’t necessarily have a time crunch to return to the US on the same date as my wife, and I have a good stash of Choice points to book affordable accommodations for a solo traveler in Tokyo for the two extra days (or to make a quick solo trip to Hiroshima). The thing is, I don’t drink much and I’m not much of a foodie. Is JAL first class just a waste of points for someone like me who is very happy with a modern business class seat with doors, like STARLUX offers?
