#ComicBytes: Five worst things Professor X has ever done
What's the story
Professor Charles Xavier or Professor X is one of Marvel's most powerful telepaths. Although his good intentions make him a superhero, some of his actions are pretty questionable. Professor X has always tried to fight for the rights of his fellow mutants. Even if he doesn't follow an extremely violent path to do so, he has done things that make him a bad superhero.
Death
Professor X faked his death to hide from alien invasion
Professor X once faked his own death. In Uncanny X-Men #42, he supposedly 'died' in the arms of Thomas Halloway, the Angel. But in reality, Xavier used a dead changeling to trick his students into believing that he was gone. While his students, allies, mentees, and closest friends mourned his loss, he faked his death to hide from an alien invasion.
Contingency
He created the Xavier Protocols for killing all the X-Men
Like Batman, Professor X also created a series of instructions on how to kill every single X-Men. Although this 'Xavier Protocols' is sort of a contingency plan in case any member goes rogue, it has caused a lot of trouble. In fact, the Xavier Protocols has fallen into the wrong hands many times endangering the lives of several mutant heroes.
Dark Phoenix
He is indirectly responsible for Jean becoming the Dark Phoenix
When Jean Grey was young, Charles put a block in her mind to restrict her from accessing the full extent of her psychic powers. Though this was done to save Jean, during an outer space mission, the Phoenix Force entered her body and unlocked the mental block. As her powers came rushing back instantly, Phoenix amplified these powers and almost destroyed the world.
2nd X-Men
He erased the existence of an entire X-Men team
The second team of X-Men (Wolverine, Storm, Nightcrawler, and Colossus) was created to rescue the original team from Krakoa. However, Xavier already had sent a second team for this mission. Unfortunately, all the members of this team were killed, barring Scott Summers (Cyclops). Instead of honoring the fallen mutants, Professor X wiped Cyclops' memory and acted like the mutants never existed.
Onslaught
He unintentionally created Onslaught, who almost destroyed the universe
During a deadly confrontation with Magneto, Xavier absorbed his negative emotions. This broke his morality and unintentionally created a paradoxical monster known as Onslaught, who had the powers of Prof X and Magneto. With its immense powers, Onslaught killed the Avengers and Fantastic Four and destroyed the world. Thankfully, Franklin Richards and his incredible powers saved the Marvel Universe from ending.
