Same conclusion I've come to about the passage.
Again, our eyes, hands, and feet are very valuable to us, nobody would cut them off. Jesus is saying that no sin is worth our soul. Our soul is so important, that if your eye causes you to sin, or your hand, or your foot, as valuable as they are, you would be better to gouge them out or cut them off than go to hell. So, he is saying our soul is what truly matters and what is most important and should be our priority.
We should not put any sin, like being wealthy or powerful before trusting Christ and being saved.
