In many cases, Morbius isn't considered bad. His character is complex and has various motivations and actions that can't be simply labeled as bad. It's more nuanced than that.
In the comics, Morbius is a complex figure. He struggles with his newfound vampiric nature and often finds himself at odds with both heroes and villains. His powers include enhanced strength, speed, and the ability to fly, but his condition also brings moral and ethical dilemmas.
It depends on your preferences. Some fans think Morbius is great in the comics for his unique powers and complex character development. But others might have different opinions.
Morbius is indeed based on a comic. The comic served as the foundation, and the movie built upon it, bringing the character and his story to the big screen.
