Should cabled hat be blocked?

[MarthaStarWarsFan]

Hello,

I'm not sure if this is a dumb question or not, haha!

In between long stretches of my Doctor Who Scarf knitting, I'm making the Basic Cable Cap from the HeadHuggers site using Malabrigo Worsted Weight Yarn.

With a cabled cap should I worry about blocking?

I made another cap this week as well with the same yarn and it seems to fit fine, would there be benefits to blocking it anyways?

Even without cabled stitches, should I always block wool caps?

Thanks so much for help!
