No.
Should they have made more ethical compromises, particularly in the technology sharing arena, perhaps. Gone as low as to murder innocent sentient creatures? Absolutely not.
I do think their stay in the delta quadrant should have been rougher. Maybe been low on resources a little more, had a few more growing pains with the Maquis crew as opposed to instant conformity except for three guys in Learning Curve. And they should have had open conversation about whether perfect Starfleet behavior really makes sense stranded alone in the delta quadrant when you're desperate.
But they should have arrived at a compromise far short of crossing the line of murder.
