How was cronus evil?

Cronus, a Titan in Greek mythology, is often considered evil due to his ruthless actions to maintain power. Fearing that one of his children would overthrow him, he swallowed each of them at birth, demonstrating his willingness to commit horrific acts to secure his throne. His tyranny and fear-driven rule ultimately led to his downfall when his son Zeus freed his siblings and led a rebellion against him. This cycle of violence and betrayal illustrates Cronus's malevolent nature.
