Strange human thinking - different half of measures

For some time I wonder and ask myself how that us, the human beings, judge always with two half of measures.

For example we say: You can't take a life, you are not God to decide about life and death and to decide if someone deserves to die.
Ok, agree with you! BUT for God's sake then how can you decide if someone deserves to live? For example saving someone who is almost dying or already dead, bringing him/her back to life.
Oh, I get it, life is cool, someone in history decided that life is cool but for our ancestors was a real honor to be sacrificed for some whatever Crops God. In Africa are tribes that are still letting the weak ones to go and die, like in the wild. We, the "civilized world" are saying that this is no way, they must be saved and bring them our civilization and manners, by the way which manners?!?!
So you say you don't feel God enough to take a life but you suddenly feel God enough to save a life - half measure.

Cuteness: Oh, this is my favorite! You see a nice squirrel and you pee on your pants with cuteness, you see it's kin, the rat, you jump onto the closest chair shouting that someone should kill it and kill it NOW!
Cats, another example, you see one and suddenly you are in love "oh how cute", the cat is chasing it's tail "oh, it is terribly cute", the cat enters in a chips bag "oh, adorably cute!" ... now you see a dog "cute", dog enters bag "ah, maybe is not so smart, but at least is cute", dog chasing tail "this dog is dumb!"
Even rodent lovers prefer a guinea pig instead of a rat or a white lab mouse instead of a common gray one.
Why? is beauty so important? If you are ugly and live in sewers you need to die but if you have fluffy tail or ass kissing attitude you deserve a life? Wake up people! You realize that the first hours of your life you looked like shit? Should someone killed you because you were such a nasty looking newborn?

Womanizer vs Whore: Keep in mind that I am a male but for fuck's sake why a woman who changes men like her dirty underwear is a whore, every one who does not want to show her the ceiling is hating her, sometimes even the ones who are willing to park their car still are thinking nasty about her that she is a bitch, she is a disgrace bla bla ... you know it, you do it everyday. "Who? that whore who slept with the entire class? What a bitch!" And this is equally judged my male and female population!
Now we take the male whore, here we judge him a bit different. The females are calling him a womanizer but still they  are willing to be around such a successful male, if he nailed so many girls and dropped them next day ... well, then he is worthy, knows how to stick a log into the fire. "I know he loves girls, but I will show him that I can be the one to make him change", or "Oh, he is so experienced with girls, why not? He knows how to deal with a female" ... yeah right, use you, like the whore does with men. Ok, if the ladies are looking a bit weary but sill charmed at the male whore, then the male population cheers his deeds of bravery, his long list of sheets he was into, the money brought to condoms industry and probably without knowing they are also cheering the fact that he just screwed their partner / wife / girlfriend.
I say whores are whores gender independent, low characters, heart breakers, without self control around opposite sex, selfish trophy hunters. But then again it applies only with half measure. Or you can love whores ... but then again with half measure.
 
Try to think outside your box! Ask yourself questions, look from other angle, change the perspective, argue with yourself, doubt the morality and immorality definition but don't do it just with half measures!
