Yes, but I see that as a distinct lack of empathy.
Lazy brain also doesn't have issues thinking about how to benefit itself over others in contrast of the way it can stop being emphatic about others.
We were hardwired to that.
And the only way to evolve is through powering through urges like that 'laziness about empathy', or just live as we always have (but now on global destructive level with basically 0 realistic/actionable chances of going extinct).
