undeliberate
Done without thinking
Undeliberate means not done with conscious intention or forethought—accidental, spontaneous, or unconsidered.
An undeliberate gesture reveals something the person didn't mean to show.
The insult was undeliberate, just a slip of the tongue.
The word is uncommon; unintentional or accidental usually serves the same purpose.
