Although, I do believe that things should not be unnecessarily complex. Make the complex as simple as possible, but don't give UP complexity for absolute simplicity or human development will stale...
Sometimes, it is the unclearness that allows for beautiful expression in life.
A phrase like "God is love" can mean so many different things to different people depending on how they define the words. The simplicity allows the individual to make more personal and abstract (and almost spiritual) meanings.
Definitely. Integrity is honesty. Honesty is simple compared to memorizing the lies told to others. Honesty is also more natural. You are just being yourself existing. We need more people with honesty who isn't afraid to break meaning social constructs.
Purity I would have to disagree because purity can mean many different things. It is subjective and depending on your philosophical/religious/spiritual views, purity may mean one thing for a person and opposite for another.
For example, for some, Purity is naturalness , so sex would be pure, for others it is a impure concept.
