As someone with decreased empathy, I think I have a unique take on this.
If you mean Affective Empathy... yeah, it definitely can be if you don't have a healthy amount of it. I used to be hyperempathetic as a young child, but lost all of it when I got older.
I still feel it rarely. Specifically for one person in particular. It's a double-edged sword—it's an extremely bonding experience to feel emotions you haven't felt reliably in years, but it's also overwhelming and vulnerable.
