Humanity is a matter of genetics. Lack of conscience is an emotional and mental disorder. The soul is a matter of opinion. Though they may do terrible things, they are definitely human.
Conscience is an aptitude, faculty, intuition or judgment that assists in distinguishing right from wrong. Many people exist on a scale of conscience, especially people on the autistic scales, as well as sociopathic people. This is completely different than the concept of a soul. The soul is a religious and philosophical idea, so there is no way to definitely test its existence.

This must surely depend upon your definition of what it means to be human. A sociopath is still human, but one without remorse or grief, they manipulate and control, and are unlikely to change. It may be hard to understand the mind of the sociopath, as most 'normal' people will be relatively unable to turn off their conscience, however these people deserve understanding as much as any other person, and once you understand them it might perhaps be easier to guard yourself against them. Yes, they are human. With regards to the soul, surely everybody has a soul? If you believe in such things then we must all be born with them, including sociopaths. Maybe their lack of empathy would cause their soul to be stunted. I think that, in the case of this question, you should be more specific in regards to the definition of the soul. Perhaps you see (or indeed, do not see) a difference in being 'human' and being 'humane'.
Only human beings have conscience or reason. Animals are provided by the mother nature with irrational instincts.
When God created living creatures only in human did He breathe the "breath of life" and thus create a living soul, therefore "breath of life" differentiates the human from all other living things.

There were never human-like creatures on Mars, as far as we know.
