The answer makes it harder for me to know if the riddle is correct.
My prefix may be your end
My suffix is a question
Sadly my infix can´t be together with my prefix or suffix (normally) :(
My suffix is short and mostly asked by young people
If we don't care the prefix may be our all end
One of my edits may be a big hint on my small infix
Don't worry there are so many specialist fighting against my prefix
