Etherious.

Number of victims: Countless.

How easily can Zeref get rid of them? With a snap of his fingers.

Are there any moral issues with getting rid of them? Some. They are like his children after all.

Does he have any issues with getting rid of them? No.

For people who want to bring up normal parent-future criminal child relationships: Normal children are not definite (as opposed to potential) homicidal WMDs. That still doesn't stop the parents from being blamed in quite a few cases, sometimes rightfully, sometimes not. Depends on the case.

For people who want to bring up creators of WMDs: Normal WMDs are not autonomous, homicidal sapients. That still doesn't stop many people for blaming the developers.

Zeref is definitely evil.
