> I think the biggest issue is to not have empathy for sinners and you think you are a saint…

At least that's only hypocrisy (assuming you are not, in fact, actually a saint--you might have developed habits and values that mean you are not likely to sin in that way.) At some level it's not even a problem: you want to aspire to be a better person than you are right now, which means you will hold values that you do not currently measure up to.

But thinking you are a saint because you have empathy is perniciously self-righteous. You can see something similar to this in the progressive movement right now, for instance.
