If you set out do something with specific intentions, and fail to accomplish your goals, you are technically a failure. Doesn't matter what you've been through or what you set out to do, if you can't do it, you are a failure. It may not be your fault and one does not have to stay a failure forever. If you want to do evil and end up doing good, you failed. Same goes vice versa.

A man who desires to do evil and does good is not a good man. Just a failure.

The CEO has responsibilities. Corporate decision makers have many pressures and motivations that effect the decisions they make. I am in no way trying to defend CEOs or Corpos that value profit over people. To me, at least, that is inexcusable. But, I'm naturally very inquisitive and often play the Devil's advocate to get a glimpse into the minds of people I disagree with or even hate. People function on many different levels, and it's important to understand that. The CEO does have a responsibility to his shareholders to produce as much profit as possible. But, he is still Human and it is dependent upon him, where the line is drawn. Is he willing to sacrifice profit to save lives, or is he willing to sacrifice lives for profit? What matters more to that individual, his wealth, or his conscience (assuming he's ever had one to begin with)? The answers to these questions vary from each individual, as do the reasons they have for giving them. For me, it is simple. No matter how you flip the pancake, a Human Life is ultimately more valuable than any dollar amount.

But, that being said, it is much easier to make money than save lives.

No. It is not moral for anyone to prioritize profit over Human lives or the well-being of others.

Waves are not alive. They are not born. They don't live. They are just water in motion, and when a wave crashes, it does not die. The water relocates.

But a Stoic one is not the only solution to this problem. You could also try to empathize with your toxic roommate. Maybe they are going through something truly difficult and have no one to talk to or any constructive ways to cope. You could help them in that situation, and show them that projecting negative emotions towards others will not help relieve any pain you may have. Granted, I don't have a full understanding of your current situation, so don't misinterpret this, but you could try to be a friend to this person, if that's possible.

In order to handle this situation in a Stoic manner, you must first categorize what you can and cannot control. You can control where you live, you can control where you "see" yourself living, and you can control whether or not you confront this disrespectful roommate. You cannot control the behavior of another and you cannot control his/her reaction to being confronted by you. So the decision is yours, to either move out, convince the others you live with to kick him/her out, or confront him/her and hope that he/she understands your concern and tries to change his/her behavior. Decide what's right for you. Would you like to give him/her a chance or just skip all the difficulty and anxiety by moving out and being happy somewhere else with someone else? Just remember that you will sometimes suffer regardless of what choices you make, and the only thing you can do about it is control how you react.
