His extreme cruelty and predatory blood lust when slaughtering the clones may stem from the fact that he is intentionally trying to see and treat them as inhuman to prevent his actions from taking an emotional/mental toll on himself.
It makes perfect sense. We already know Accelerator isn't inhuman since he decided to save Last Order, sacrificing his own health to boot, and even took the onerous job of looking after her. In light of that it's more than obvious he made a firm mental decision not to view the clones as humans during the experiment. He wouldn't otherwise have been able to either keep going through the experiment or remain sane (or as sane as he is, which is a little less than any average joe). Keeping this in mind, even blowing up a clone like he did in this episode is only logical: He can't afford any mercy or sympathy, lest he accidentally lapses into considering them human, which would have marked the end of the experiment for him.
