Deleting the usr directory will not be fatal, but your system will be
rendered unusable. usr/ does not only include user installed apps but
also the other apps which makes up your working OS (they are in the
/usr/bin). I don't recommend deleting the /usr directory to make
space. Instead try removing applications you don't need. Also,
sometimes the apt cache gets too big and should be cleaned up to free
space. You can do it manually if you know what you are doing or you
can use some app to do that like 'Computer Janitor' (preinstalled) or
I suggest 'Ubuntu Tweak' (try this).
