I'd guess that they'd say "it's just exploding bodies and a naked girl", which isn't really true if they watched the entire series (only 13 episodes sadly). Spoiler: Warning: Spoilers inside! It's disgusting how inhumane humans can be, and despite that Lucy (a Diclonius) was made to eradicate the humans she was taught to be respectful and lovable towards human beings, so it's possible to change but if there's a moron with the objective to kill her then that's an order a whole army's going to take. At the end of Episode 13 we see someone knocking on the door, and despite that she killed Kohta's sister and father I do wish it was her because she was the closest to him which always loved him. Yuka also did love Kohta but it felt forced because he didn't have those same feelings for her, and well, she's Kohta's cousin.
