First introduced with a brief appearance in The Incredible Hulk, Wolverine has taken on many heroes and foes, and has done so passing through a great many iterations.
As a formidable member of the X-Men, he’s been clawing his way through our comic book pages for decades, and had many an adventure along the way. But, while skirting the darker side of heroism for so many years, Wolverine has sometimes been known to drift too fa, and cross the line into depravity and villainy.
There are accidents, acts of poor judgement, the occasional brainwashing by villains as well as a variety of other mitigating factors to pardon some him. But then there are also simply times when he has carried out some horrendous acts, fit for a common criminal, or perhaps even barbarian, without any such excuse to fall back on.
He might be the best at what he does, but everyone knows that what he does isn't very nice...
10. He Tried To Sleep With Mary Jane While In Spider-Man's Body
The early 2000s was a time when the body-swap trope was all the rage, and comic book characters have had a rich history of such stories themselves. One such example is the time when Jean Grey decided to punish Wolverine for his inappropriate advances by using her powers to make he and Peter Parker swap bodies.
This was the event which led into the storyline of Ultimate Spider-Man #66-67, printed in 2004.
While a punishment this may have been, Wolverine having to put up with the tedious nature of high school trivialities and the like, he soon discovered there were things he liked about living the life of 15-year-old Parker - such as his girlfriend Mary Jane Watson.
So, making the most of being a teenager again, he did what any morally upstanding hero would do and attempted to sleep with her, leaving the real Peter Parker to apologise for his uncharacteristic behaviour when they were returned to their own bodies.
Fortunately for Parker, Mary Jane forgave his apparent lapses in character, stating at the end of the second issue of this story that she didn't want to try that thing "he'd" attempted until they were older.
