Personally I wasn't counting the movie villains just in the the series and secondly he may be the center of attention but the he hardly is ever in the spotlight until the final battle of the sagas unlike Natsu who takes the spotlight multiple times before the final fight. And Goku's moves not killing his enemies is a way shows his care for other living beings or the strength of the great villains of the series.
