If they are so simple and small that their runtime complexity with regard to manipulating matter is close to 0-- then when you kill them, they die so quick their reaction is only enough to output a bit of data. I for one feel like its moot to debate whether we would feel pain if a giant sliced our head off at the speed of sound. Thats just death-- a fast death with no sensory systems fast enough to notice. Now if youd like to debate about whether death by itself, painless death, is amoral, that would be interesting and relevant to these critters..
