Perhaps, but only in the same way psychopaths are sentient too. 
That is a very good point!
We are going to create sentient machines at some point.
All the machines we have create so far are psychopathic.
So before we create a sentient machine we dam well better program it with a conscience and sense of morality.
Not that any of this matters.
By 1000 years after the first sentient machine is created, humanity will be wiped out. Sure there may be a few Eskimos that survive here and there but our civilzation will be gone. The sentient machines will take everything.
But hey, it was nice knowing you guys!

We had a good run.
