I think the whole series has many sad moments.
Like when Lucy was betrayed by one girl she trusted and that costed her dog's life. Having your friend/pet killed in right front of you is enough to make anyone a psychopath killer.
It's also sad when Kouta lost his father and sister, Kanae. One lie screwed his whole life up and further screwed Lucy's.
Nana has her her share of tragedy. Like losing her arms and legs, the torture featuring cannonballs and watching "Papa" die.
Mayu had been under the influence of a horrible abusive mother and a pedophilic stepfather, which caused her to run away.
In the special OVA episode,Lucy had another tragic event which was the last straw. In a flashback, she befriended a girl who liked her despite appearances, but Kurama's pursued them. Lucy protected the girl from the firearms, but then, that very girl took a sniper's bullet meant for the diclonus. Upset and promising she would help her, Lucy made a deal with Kurama, she come along with him if he helps save her friend's life.
However, Kurama's part of the deal became unfulfilled, as he mentioned to Lucy, in confined straitjacket mode, that the girl had died. Tears flowing from her mask, Lucy's last chance to go straight was shattered as she warned Kurama that she make him suffer by killing those close to him, should she escape.
And finally, Mariko andKurama perishing. A redeeming side to this is that they're now togather forever.

This anime shows a great deal of realism in proving the sadism of humans. From the kids to the scientists, a large majority of humans in the series prove to be sinister.
The Diclonus are really the victims, suffering the sins of mankind.

Tragedy is what the main chracters all have in common. Some traumatic events in their past.

Holy balls! Moving to the spoiler section ASAP.
