i know that once you do bad things in the world you aren’t considered pure or innocent anymore, but well maybe you aren’t innocent but you can be pure?? if you did bad things can you be pure again?? this is not about religion but rather the truth of being a person yea!!
I am going to need you to define what it means to you to be “pure of heart”.
There is a decent chance that you will find an answer to your question by doing this.
