I saw a documentary on the subject where that was acknowledged in this particular case, the suffering being an important factor. I can't remember the documentary title, but the example was given of humane, even pleasurable, similar method to use instead of injection etc and it was dismissed angrily by pro campaigners for those honest and believable reasons. That's not to say it's a majority opinion - so I agree with your objection to that generalisation, but it's definitely a reaction of some who are pro-death penalty.
