Either is fine. If you can bend it, bend it. Though with alloy and even with some steels, you might get some weakening or fatiguing of the metal at the bend that might either show immediately or in the distant future. Will it be a sudden break that causes you or others injury? Who knows.

But new bars can be as cheap or expensive as you want them. You doing it yourself? Some can wrap bars intuitively and do it nice the first time. Some never can wrap them pretty.

But also as other's pointed out be sure it's not that a lever got pushed or the bars rotated in the stem.
