@Al-Fatihah,
of course none of that excuses the fact that your theories on love and lust seem like crap
do people do horrible things when there is lust over love, sure, but that doesn't mean that lust itself is bad, it's what you do with it, it's a tool that you can use in your life, if i have a knife in my pocket and i use it to stab every child i see,than i and my knife are an instrument for evil, if however i use it to cut slices of apple for every child i see, it and i are an instrument for good
if i lust after a woman, it can be a good thing or a bad thing, if i'm only after my own desires it does the woman no good, but if she's okay with it it's perfectly fine
and as for love, if i love a woman but don't lust after her, than she's no more than a sister or mother or friend, in a marriage love and lust go hand in hand (or are you going to say me sex is only for procreation), if not then it's a friendship not a marriage (and yes married folks should be friends, but sex does enter into the equation, and lust is part of sex)
it's possible to love and lust and have everything be okay
