motiveless
Lacking any purpose
Motiveless describes an action without apparent reason or purpose.
A motiveless crime baffles investigators because it lacks the usual explanations—greed, revenge, passion.
The word often appears in discussions of violence that seems random or inexplicable: a motiveless attack on a stranger.
Something motiveless may simply have motives that remain hidden.
