You agreed to also removing dependent packages. Always think and if not 100% sure go old school and check to be sure;
$ rpm -e --test mingetty
error: Failed dependencies:
mingetty is needed by (installed) initscripts-8.54-EL.1.x86_64
I'll leave it to you to see what the output from the typed command: rpm -e --test initscripts
warning it is not pretty, but it will give you an understanding of why this happened.
