You can experience basically any emotion in response to this.

• Disgust for seeing this happen
• Anger towards those responsible for it
• Frustrated that these deaths still happen despite all the work put into preventing them
• Overwhelmed by the state of the world and your powerlessness in fixing things.
• Fear for your own life or that of loved ones who can realistically find themselves in a similar situation
• Happy that you made it out alive when you went through a similar situation
• Grateful that you don’t live in an environment where this is a common occurrence.
• Motivated to get back to work towards your dream because of the reminder that life is short.

And that’s just a few off the top of my head. It would also keep out autistic people who can’t read their own emotions.
