Cripled, Blind, Deaf

alright i dont get this part but why does god create these types of people, have these injuries or issues with their bodies from birth. i mean its understandable if it happens later but why does it have to be something that they may have at birth. are just might have some kind of diformaty, or injury that will cause them to never be accepted in common soceity. to me i believe this is a type of cruelty to put on someone. why would he not just put eveyone in a healthy and good manner and make it just.. right. dont you dare say that this is to show gods power because its not.. showing gods power is blowing up a volcano, or striking lighting in a good picture. but gah, why this.. this is a type of.. curse. they say that in different religions if you have something like this then you were a horrible person in a past life and that you deserved this and well i could go along with that.. but why does someone even deserve this. god should be loving and all of that but why curse the inocent from birth and make them less then they ever could have been. it doesnt make sense why some dont have the opportunities that some one else has just because of a physical difformaty or a mental, or just other issue that someone might have. its something that is just wrong in my eyes. he should have never have created these injuries, these issues int he first place because it will always be that these people are less then anyone else is some peoples eyes.
