I wouldn't use the term "evil."Struggles? Probably.
But that also means potential.
A lot of potential.
Hard aspects are difficult to ignore.
More often than not, we're faced with them in the form of internal and external challenges and conflicts, and how we deal with those challenges defines us and our lives.
It's important to work on self-awareness and honesty with hard aspects. You have to face your self and be willing to come to terms with some ugly parts of your own psyche.
I believe many people are unwilling to do it naturally so they experience all kinds of dramatic events and personal and interpersonal crises. So they can become aware and fully conscious of what needs to be improved and adjusted for optimum functioning (or the "evolution of the soul").
