A hypothesis:
??????? ?????? ??????? ???? ?? , ??? ?????, ?????, ???? ????? ???? ????? ????- I believe all the middos you mention are all different sides to the same coin – living in an illusory reality. It’s the opposite of truth, which is good, so I think it may be self explanatory why these middos i.e. living an illusion are the worst. It’s the farthest away from the truth.
Gaavah – self explanatory. Having gaavah means living in the illusion of “Koch v’otzem yadi”
Taavah – living with the false assumption that what you want is THE most important, you’ll stop at nothing to get it. Forgetting that Hashem is the One that should determine your wants, and that other peoples feelings should come into consideration.
False Gaavah – Building a false reality where you are the best at everything. (Can’t do teshuva in that case, because what’s there to do teshuvah for? I’m wonderful.)
Loving bad – that’s also creating a false reality, seeing bad as good and good as bad.
I used second person just because it was easier. I ‘m not talking to anyone specific.
I have no idea if I am right or wrong, and I did not check the context of your quotes. This is just a hypothesis.
P.S. If you’ve ever met a person who has Narcissistic Personality Disorder you can see clearly how all these middos tend to exist together.
