Physically yes I would think those pills are much more easier and convenient.
Also from theological point of view since you do not know that you would have gotten pregnant if you had not taken the pill you can at least tell to yourself (and maybe even be correct) that the pill did not do anything that would not have happened anyway.
Principle is about the same for one member of the execution squad being issued blank ammunition
In some cases, one or more members of the firing squad may be issued a weapon containing a
blank cartridge.
[2][3] No member of the firing squad is told beforehand if he is using live ammunition. This is believed to reinforce the sense of
diffusion of responsibility among the firing squad members. This diffusion of responsibility makes the execution process more reliable because the members are more likely to aim to kill if they are not entirely blamed for it, or if there is a chance they did not fire the lethal shot. It also allows each member of the firing squad to believe afterwards that he did not personally fire a fatal shot
[4]—for this reason, it is sometimes referred to as the "conscience round".
According to Pte. W. A. Quinton, who served in the
British Army during the
First World War and had the experience of serving with a firing squad in October 1915, he and 11 colleagues were relieved of any live ammunition and their own rifles before being issued replacement weapons. The firing squad was then given a short speech by an officer before they fired a
volley at the condemned man. He said about the episode, "I had the satisfaction of knowing that as soon as I fired, the absence of any recoil [indicated] that I had merely fired a blank cartridge".
[5]
In more recent times, such as in the execution of
Ronnie Lee Gardner in the American state of
Utah in 2010, one
rifleman may be given a "dummy"
cartridge containing a
wax bullet instead of a lead bullet, which provides a more realistic recoil.

Morally speaking fascinating stuff.
