unselfish people can engage in lust just as well as a selfish person, the difference for an unselfish, lusty person is that they are more giving than is healthy for them, is a person selfish for in wrath striking at another person for another...love for that matter in my opinion can be more detrimental than a selfish action against another.

but placating isn't really a sin or anything that deals with human nature or emotion, but satisfying the need of something, as a matter fact it'd be the opposite of selfishness.

when words become questionable for me, i resort to the dictionary, Webster's made it his life to point out the proper meanings of words, but I've always been a dictionary/vocabulary junkie.

my philosophy Mr. Sixx is the philosophy of my own design...but Kant is most comparable to my ideals, I'm not sure why German philosophy of that time is so appealing for me, who was the poet...Goethe? It seems i came across him reading Kant's idealism versus materialism. *shrugs*

honestly, it's been a long time since I've dabbled in any proper philosophy, anything new in the world?
