Yes, well, we were at first discussing alternate scenarios, how it could have made sense to beam down his crew. The dialog in the episode said that the
Constellation had been hit and lost power. But
@Maurice's scenario involved other assumptions, specifically that Decker intended to lure the machine away. You said that didn't make sense, unless Decker knew the crew might die.
Then, I asserted that Decker had intended a kamakazi run. We saw him issue the order to continue to attack without veering off after the ship had been caught in a tractor beam and was being pulled inside. It doesn't mean that Decker was intending to carry out a suicidal attack initially when he assumed command of the
Enterprise; I agree it didn't seem like he was. But by that point he had total target fixation.
So, getting back to what started this discussion, I think it would make sense to beam down the crew if Decker believed he could lure the machine away and he thought that by doing so the ship would eventually be destroyed. In other words, if Decker thought it would be a suicide mission. What
@Maurice said was that what could ruin his plan would be that the machine would lose interest in the pursuit and go back to feed on the planet.
