Design decisions can easily allow you to implement the same functionality in an order of magnitude less code.
Also, research shows the number of bugs per line of code is pretty much constant across programming languages and kinds of programs. So reducing the number of lines of code will almost certainly reduce the number of bugs, statistically speaking.
