Is there a way to enjoy fast food like McDonald's without feeling guilty or facing negative health effects?

My family kind of abandoned me when I was younger. That really hurt in a lot of ways. Now they are back and want to help. Should I accept the help or decline?
If a robot apocalypse happens, will you trust the computer scientists to tell you what to do? Since robot apocalypse is a problem caused by computer science and computer engineering, is it absurd to think we can use even more of them to mitigate it?
