Things I Question/Hate About Diabolik Lovers

So, we all know that Karlheinz uses people as experiments and test subjects and then kills them when they fail or if he doesn't get the result he wants, right?

So then why the FUCK are the Mukami's still alive?

Like, we find out that none of them are capable of being Adam and that the only reason they were "saved" was so they could become Adam and fulfill another one of Karl's experiments.

But since they failed and no longer have a reason to live

WHY THE HELL DIDN'T HE KILL THEM?

WHY ARE THEY STILL ALIVE?

He even threatened to kill them if it didn't go right the very day he found them!

Unless there's something I missed, I can't be proven wrong.
