I lost an uncle and an aunt in 6 months ... why am I not complaining ?? Is it that i don't care about them ??hell no it's not that ... when my uncle died I was so stunned that crashed my car ... still wasn't complaining ...
It all depends on how a person approaches it .. Basicly, we agree that it's all God's will. but you're questioning his justice. Personally, I believe that God wouldn't take anything from me unless it would prevent bigger harm on me or he gives me something instead either better or as good. You would ask how can someone get something better or as good as a mom. There are lots of possibilities, for an instance you would never know how he would turn out if his mom was alive.
All in all, If you believe that the Almighty exist shouldn't it be easier for you to comprehend that he's just ?
