Difference between "my" an "my own"
"My own condemnation" can be reworded as "the condemnation asserted by myself"; whereas "my condemnation" is very ambiguous, and can mean either "the condemnation asserted by myself" or "the condemnation I face/endure". Therefore, the added "own" provides much clarity as to what is meant.
When you are living with your parents then you can say to your friend, "This is my home" but when you are staying far from your parents and you have your own home then you can say to your friend "I'm living in my own home"
