Paragus

Paragus is Broly's father in the original Dragon Ball Z movie continuity. A cunning and manipulative Saiyan, he uses a mind-control device to keep his son's Legendary Super Saiyan power in check while plotting revenge against the Vegeta royal family.

The wiki source describes Paragus as cunning and manipulative, using Broly as an instrument of vengeance rather than treating him as a son. He suppresses Broly's personality with a special headband device and tries to weaponize Broly's power against the Vegeta royal family, behavior that reads more as exploitation than love.

Paragus is a bad guy. He poses as a loyal subject to lure Vegeta into a trap where Broly will destroy him, harbors a vendetta against the Vegeta royal family, and uses a mind-control device on his own son to enforce his plans for revenge.

When Broly's conditioning breaks down in Goku's presence, Paragus loses control of his son entirely. In a desperate attempt to escape the destruction of New Planet Vegeta by an incoming comet, Paragus tries to flee in a space pod, but Broly catches him and crushes the pod with him inside before hurling the wreckage into the comet.

Paragus harbors a vendetta because King Vegeta ordered infant Broly to be executed when his power level registered at an extraordinarily dangerous level. Both Paragus and Broly survived the assassination attempt and the subsequent destruction of Planet Vegeta, but the experience left Paragus obsessed with vengeance.
