Sabotage is a deliberate action aimed at weakening another entity through subversion, obstruction, disruption, or destruction. One who engages in sabotage is a saboteur. Sabotage is in general, a crime, although there are exceptions. For example, while Marvin and Wendy were aboard the submarine known as the Sprite, they learned that Doctor Pelagian was going to unleash deadly tidal waves. So they attempted to sabotage the machinery. But they were not successful.
