Since its your money, you are free to spend it however you want. You don't need to justify it. But if you
want to justify it, set your own standards. Upgrade when you can tell exactly why you need the upgrade.
Some people might need more MP, but most people don't. Some people like wider angle perspective of FF, but many people don't need it. Some people want fast burst mode of K-3, others want compact form of K-01, and some want a big monster with battery grip like K-1 with Sigma 35mm art on top.
You are not a bad person for sticking to the camera you like, and you are not a bad person for getting the newest, biggest camera you can find.
Edit: I still use K-01 and occasionally K-r. When I upgrade, it will be because these are no longer functioning, or because the new ones will have significantly better ISO performance. Or if I win the lottery and splurge
