the purpose of the Mussar Seforim is not to scare you. it is to tell you what The Ribono Shel Olam wants a Yid to be. what he expects of YOU. and how to accomplish this.
when you realize and ponder how you have failed to even begin on this road, how you have failed your Father, your King, and how you WILL stand before The Judge of eternal life and eternal death, of Gehinom and Gan Eden you WILL be scared. and shamed. and if you are not, it is only because the Yetzer HaRa has his dark hands tightly over your eyes and around your heart. then you should be doubly scared.
