Is it worth to jailbreak the iphone 5c?

I want to but can you unkIlbreak it without deleting everything

Jail breaking is only really worth it if you are a modder willing to completely program the phone to exact specifications. Don't be another twelve year old kid wanting free games on their iPod…

Nah, it's a good phone. Plus, most people who jailbreak their phones are novices, and break their phones forever.

Jailbreaking allows you to install third-party applications, tweaks, mods, themes, useful utilities, and other content (called "packages") from Cydia, the jailbreak equivalent of theApp Store on iOS. Jailbreaking essentially allows for you to further customize and enhance your iOS device beyond the limits that Apple imposes.

It will not delete anything. But you need to backup your iPhone for safety.

Here is tutorial, you may refer to it to have a try.
