I don't know how you can like dogs but be a cat person at heart. 😄 Of course, one can love all animals. I, for one, love most of them, but my last dog helped me see through canine nature, especially after he tried to kill me a few times... (bekloppter Malinois)
No, I don't like dogs anymore. And yes, I love cats' sense of humor too. Even their capriciousness and their treatment of us as masters to servants.

I have known a few good natured dogs. An untrained or badly trained dog is no one's friend. That is why I will never adopt a grown dog. Most important, it should love cats

That's exactly the point - 'untrained or badly trained'. This means that one has to devote endless amounts of time to training this dog, as well as being constantly engaged with it. The cat, on the other hand, does not lend itself particularly well to training. It doesn't need it either.
You are so right about adopting grown dogs. Things can turn out well, but there is always a danger, a huge danger that something bad will happen because of things from the past.
