Tantrikas are all always responsible for the results of their actions even if those results were unintentional. - Illusory Advice

From the perspective of karma, a complete karma requires intention, the act, and satisfaction about the completion of the act. Hence if there is awareness (intention) and somebody gets hurt through the action, whether or not it is a complete karma will depend on whether the instigator is satisfied that someone got hurt. If they are not and regret that there was harm, then this is not a complete karma. Tantrikas are all always responsible for the results of their actions even if those results were unintentional. If someone has been hurt through your actions—whether or not there was intention, self-control or awareness—you remain responsible for the outcome and should try to help the person who has been hurt.
