Modern day tragic heroes?

So, I have to write about a modern day tragic hero, but I don’t know much about celebrities or well-known people that have made a big mistake. My teacher gave us examples like Britney Spears and Lindsay Lohan, but we aren’t allowed to use them.

All I really need to know is someone that could be considered a tragic hero and some personality/character traits that contribute to what they did wrong.

btw a tragic hero is someone that is an overall good person with a few strong traits which lead them to making a big mistake in their life.
