Well technically probably so. Nakedness was a symbol of purity and innocence. We lost it when we sinned and became aware of evil.

Animals aren't free of "defects". There are some cases of animals with three heads, five legs, etc...

Does that make that normal or natural?

Same thing with a psychopathic serial killer. S/he can say thats how their mind was made and they can't help themselves, but that doesn't mean we can't "stop" them in some way.
