Oh dear. Deleting the game outright (or not) on your PC is your decision to make and only yours. However, I reckon you would have punished yourself by doing so. Also, if you run an OS in German, it is perfectly sensible to have the game run in this language as a standard. And you may switch in the options to the language you desire. It is not rocket science to go into the Options and change the language. I honestly do not understand why you would even consider making a post like the one you just did.
