My intent was to carry out my duty as a doctor, to end their suffering. Unfortunately, that entailed, in their cases, ending of the life.

I intended to do my duty. Not murder,

As a medical doctor, it is my duty to evaluate the situation with as much data as I can gather and as much expertise as I have and as much experience as I have to determine whether or not the wish of the patient is medically justified.

How can you regret helping a suffering patient?

First of all, do any of you here think it's a crime to help a suffering human end his agony? Any of you think it is? Say so right now. Well, then, what are we doing here?

Yes, we need euthanasia, for certain cases where people are in comas or too immobile to even press a button.
