First (nothing against you or anything) but would it not be considered selfish of you, in good intention mind you, by posting this thread hoping that people will think one way or another. (maybe not) But the underlining point is humans are humans and we have spesific mind sets that we all share in comon (of course there will be those who deviate from these "guide lines" but selfishness is one of them (if you were to blame anyone blame the human society and culture that you were raised in ^_^) (and now to your question)
Do you think under every good deed there is some sort of selfish intention, whether it be major or minor, lingering on the if possibility or not, conscious or unconscious?
Yes, yes, yes, yes, yes, and oh why not a little more yes... as I stated before humans are natually greedy by example of their parents, gardians, environment, or culture and as I've said before, don't get me wrong, there is some who are without this (or times when one does an act)
((greed/ selfishness)this is a blessing and weakness)
