I would suspect that there would be a different sense of empathy. Yes, the option say "no" exists and is a moral obligation. And yes, these soldiers deserve punishment.
However, there is a very notable difference between people who have led lives where they have never been to boot camp and those who have received training to follow orders. Individual experience makes a huge difference in how willing a person will be to follow orders.
There are, in fact, people who have experienced some kind of "training" to follow orders in their lifetimes outside of the military. I suspect, these differences create individual differences in how willing people are to follow doctor's orders, etc.
The fact that ANY of us will go into a room and take our clothes off because someone in a white coat in a doctor's office tells us to should give us some indication that we follow orders just the person seems to be an authority.
There are a lot of vets who discovered the worst parts of themselves via their war experience following that training during vietnam. It couldn't have been pleasant. This is not something people are anxious to familiarize themselves with.

Most modern scientists would consider the experiment unethical today, though it resulted in valuable insights into human psychology.
"In Milgram's defense, given the choice between "positive", "neutral" and "negative", 84% of former subjects contacted later rated their role in the experiments as a positive experience and 15% chose neutral. Many wrote later expressing thanks.
Why so many former subjects reported they were "glad" to have been involved despite the apparent levels of stress, one subject explained to Milgram in correspondence six years after he participated in the experiment:
While I was a subject in 1964, though I believed that I was hurting someone, I was totally unaware of why I was doing so. Few people ever realize when they are acting according to their own beliefs and when they are meekly submitting to authority. ... To permit myself to be drafted with the understanding that I am submitting to authority's demand to do something very wrong would make me frightened of myself. ... I am fully prepared to go to jail if I am not granted Conscientious Objector status. Indeed, it is the only course I could take to be faithful to what I believe. My only hope is that members of my board act equally according to their conscience...
