I tried to install a now theme for my Debian 8 Mate. I installed gtk2-engines-murrine:amd64.deb. as there was missing dependances, I deleted but, I deleted too many packages and now I don't have any theme. I tried to install what I deleted but nothing can revert (gtk2-engines is already installed,).

There is just a little problem, icons are truncated, I don't remember if there was the same at the first installation of Debian Mate : Problem with icon fixed, I restarted the computer and now, all is normal !

Try using the --purge flag. When you did apt-get autoremove package it only removed the package contents and left the config files. Try apt-get autoremove --purge <package> to remove all the files and thenapt-get install --reinstall <package> for a clean installation of the package.
