What's the difference between 「殺人者」「殺戮者」 and 「大量殺人者」?


Is it a matter of the degree of the crime like " **satsurikusha** " is worse
than " **satsujinsha** " and " **tairyousatsujinsha** " is worse than "
**satsurikusha** "? Or are " **satsurikusha** " and " **tairyousatsujinsha** "
on the "same" level?




  * 殺人 is a relatively objective word for "killing" or "murder".
  * 大量殺人 is just "mass murder", as the kanji suggest. The means of killing is not important. It's still a relatively objective term, and Wikipedia articles may prefer this.
  * 殺戮 refers to brutal and cruel mass murders, typically using rifles, chainsaws, poison gas, etc. Tabloids and novel authors may prefer a sensational word like this.
