Answer:
Use that guilt to make things better.
Step-by-step explanation:
You can't control your circumstances (such as what others around you do, where you were born, the strengths you are blessed with, or even the emotions (such as guilt and empathy) that you feel), but you can choose to make things better.
Anything works, no matter how big or small.
If you are aware of a choice you have, let the guilt you feel guide you. Choose to do something, no matter how difficult, that helps you say...
"I still feel guilty, but at least I know, because of something I did, one thing isn't as bad as it could be."
