A killer is a person that has already killed someone. The term i'm looking for is someone who wants to kill people but never does. Only has a tendency to do so, or wants to kill them but never really does.

  • did 'he' kill or torture any other living thing is his childhood? – lbf Mar 22 '18 at 13:36
  • No. but now he has wants to do so, has a feeling to do so but won't do it. – Battu007 Mar 22 '18 at 13:46
  • Are you basically saying that you know someone who might know someone who wants to kill? – Zebrafish Mar 22 '18 at 13:51

    "What do you call a person that wants to kill people but doesn't actually kill them?" ............................Angry? – pyobum Mar 22 '18 at 13:52

    @Battu007, it depends, if there's a group of people he feels hostility towards because they did something to him, I'd say he's angry and potentially violent. However if you're talking about someone who has desires of killing everyone but doesn't, then I think it's more in line with psychopathy or antisocial personality disorder – Zebrafish Mar 22 '18 at 13:57

Homicidal ideation is a term describing the mental disorder such a person suffers from. I don't know of a noun describing the person. homicidal ideator doesn't seem to be a thing. According to Wikipedia:

"Homicidal ideation is a common medical term for thoughts about homicide."1

According to lecture notes (for preparing to be an emergency nurse) on Study.com:

"Homicidal ideation is a thought pattern that may lead to actual homicide or the killing of one person by another. In this lesson, we will discuss the assessment of a person's risk for committing homicide, and related causes and management."2

    This was my first thought too. Note that this is particularly technical in the medical field and not likely to be used in conversation outside of medicine. – Mitch Mar 22 '18 at 19:57

    @Mitch thanks for your reply, as an outsider to medicine I quite like the word, in particular the ideation part (when I first read it I thought it was idealisation, as in they idealise the idea of murder). To me it sounds like a term you might hear in a series like Criminal Minds, some Googling reveals they actually have used the term on the series. – JJ for Transparency and Monica Mar 22 '18 at 20:15
