Eh, nah. Just spelling errors. XD
Because we don't know much about Dilan and Aleaeus, I think the idea of them willingly experimenting with darkness can be placed up for questioning. But regardless, they are cited as Ansem's apprentices - which sort of destroys the idea that they were pulled into the darkness unwillingly. Or perhaps it could be peer pressure.
However, I can see Even being another more than willing participant. He was a scientist and was constantly and willingly doing all sorts of experiments.
The one I want to question about willingly falling to the darkness is Ienzo. Given the evidence we have about when Radiant Garden itself fell, we know he was a kid when he fell to the darkness; in BBS he looked no more than 10 or 11 years old. I have a headcanon theory that says Ienzo was forced to fall to the darkness because of Even. Even was Ienzo's caretaker. And in the novels, Zexion' narrative quite plainly states that he genuinely hates Even. It could have been old memories of Even forcing him to do things that Ienzo wasn't interested in - and getting pulled into the darkness.
