Nedry is a criminal and thus a "minor villain", despite what some may think very few villains are actually "wicked/evil" - even the most "wicked" beings THINK they are good (Frollo never believed he was evil).. if a character commits criminal actions and those crimes are a major part of what they are then they are still a villain.

Nedry is clearly the main antagonist but since he also commited actual crimes his "antagonism" becomes villainy.

We aren't purely "wicked/evil" or we'd only host pantomine-type villains.. we also include antagonists if they put their environment/universe in enough peril via their actions.

For general purpose of wiki:

Hero - ultimately makes a universe / setting better, even with bad deeds.

Villain - ultimately makes a universe / setting worse, even with good intentions
