Yes, you can Root it without bricking. You can use the link in my signature to use CF-Auto-Root.
However, it will trip the Knox flag in the bootloader. What that means is that the phone will set a flag that you have installed a custom recovery, and so therefore you've messed with the phone. Some people are worried that this will mean that you can't have warranty work done on the phone. Some say that no one checks this. I don't know the answer to that. Some people say that using ODIN to reinstall a stock image will remove the flag, but I haven't tried it to verify it.
