The world we live

Is there a hell or is there a heaven if there is a God where's the discretion he leaves us with pedophiles and rapist but took my dad who was the greatest. There must be a reason why he left you and i and took someone like him who never made a sin. There must be a reason why he would take such a guy, was heaven getting dirty so they took him early. was Nana loanly and board and wanted someone she adored. Or was it a mistake was I suppose to take that place. If I had a choice u would still hear his voice.
