Never delete code. This is why you have git or svn, or whatever your tool of choice is. Never, ever delete code. You may think it's dumb, you may think it's crap, or useless or whatever, but in 2 years, you'll think. "Damn, I remember doing this already, don't I have some code in somewhere?" And you will.
You may look at it and rewrite huge chunks because you're a far better programmer now, but trust me, re-writing code is way easier than writing it from scratch
