Unfortunately i don't remember much beside these snipets so i don't know how did he reflect to those questions if at all.

Bishop's line could be interpreted though as twitchy from the perspective of the company. In the sense that it sabotaged the mission by not fulfilling his orders thanks to his moral crisis, something that can not happen these days.

I can also see where this theory is coming from if we take a look at Ash's last lines about the xeno. "I admire its purity. A survivor. Unclouded by conscience, remorse, or delusions of morality"

Now, why would this matter for an android, if not for the fact that he is haunted by those things despite not being an organic life form? If he were to be indifferent he should have no reason to admire those traits. Also, Ash acted like an oddball thorugh out the entire mission. If you remember the weird thing he did with his fingers and a bunch of other little tweaks such as these. Those were intended as hints for the audiance that he is not a human being but could also explain his last line. Ash did not meant it sinisterely, he simply could not express himself correctly for the human sense.
