Are Drone Strikes less Moral?

[Mudhammam]

I tend to think the more detachment then the less empathy required for the murder, which tends to increase the immorality---and frequency---of it. Thus:

Beheadings > Manned aircraft > Drones

I'd think a direct hit from a Tomahawk more moral than beheading, using the victim's suffering as a gauge.

Oftentimes limbs, even heads, are blown off a person, and they don't die, at least right away (well unless it's their head of course). And there's nobody on the other end, doing the killing, who experiences actually taking that life and watching the victim suffer; there's no accountability. The person killed by a Tomahawk might not ever even be known.
