Dean Winchester is one of the heroes ofSupernatural,who has saved countless lives.

However, that doesn’t mean that he is perfect, far from it.

He has a penchant for making poor decisions and endangering himself and the people around him.

One may admit though that his poor decisions kept the show going for 15 seasons.

Here, Dean is not thinking straight.

Sometimes, he can get carried away when he gets too focused on the mission.

However, this was a bit too much, even for Dean.

At the end of season 6, Dean asks Cas to make Lisa and Ben forget about him.

They have essentially lost a year and they will never know the reason why.

Kicking Out Castiel

It’s no secret thatCastiel has given up a lot for Dean.

However, somehow whenever Cas needs something from Dean, he lets him down almost every time.

Dean, rather than helping his best friend, kicks him out of the bunker onto the streets.

What he did to Cas is not how one should repay people who have sacrificed so much for them.

He let an archangel possess him, knowing that archangels can never be trusted.

What followed was that Michael locked Dean in his mind and committed horrible acts being in his vessel.

The Mark is supposed to lock the Darkness away and whoever bears it becomes the ultimate killer.

Dean took it on to kill Abaddon.

Unfortunately, this proved to be one of theworst things to happen to Dean.

The Mark is the world’s first curse and it turned Dean into a mindless, aggressive killer.

Things got so bad that he almost killed his best friend, Castiel.

This is not just a violation of Sam’s trust but also his body and mind.

Later, Sam is mad at Dean due to this, and rightly so.

When Dean got to know about it, he blamed Cas for Mary’s death and pushed him away.

Instead, Dean irrationally blamed Cas for everything and made both of their lives ten times worse.

It seemed like the writers weren’t sure about their relationship dynamic.

When Jack was born, Dean had wanted to kill him because he blamed him for Cas' death.

Thus, this willingness to harm someone he claims is his son is appalling.
