How to get the paid version of minecraft without paying?

I have had this cracked version of minecraft for over a year now, and it isn't very good. It will only let me play single player, not multiplayer. Is there a way I can get it for free with multiplayer, adventure maps, and mods working?

You steal a $20 and $10 dollar bill from your moms purse.
