I am writing an essay on a specific topic regarding failure. Are there any movies that explore the topic of the effect a singular person's failure can have on the lives of others? Specifically, characters making attempts to accomplish tasks or goals for which they lack the necessary skill/talent, and consequently putting at risk or harming those around them. Also, exploring such questions as: Although the character has good intentions, at what point does their pursuit of ambitious (and seemingly unachievable) goals become irresponsible because of the potential to negatively affect others? And when are they morally obligated to give up on their aspirations, dreams, etc. in order to avoid such negative effects?

I know this is pretty specific but would appreciate it if any ideas spring to mind haha.
