Depends because is it the immortal type like Hidan where you can be hurt and cut up and still be alive to feel all that pain or is it immortal as in you can't be hurt, damaged or die at all? If the first then no, if the second then yes.
Only if I was in control of my own immortality and could end it whenever I wish it to.
Living forever might sound nice at first, but most people will eventually regret it. A lot of people already struggle with how they will spend their day on a regular basis. What will you be doing for all eternity? What would you do as soon as the world is starting to bore you? You'd be stuck forever.
Helll yes i would take it are kidding?!! Wih immortality everything I do in my life and everything I am will have true meaning. I mean what's the point in doing anything when knowing everything you do has no true meaning since you will be dead for eternity eventually! Everything you are eventually disappears which makes life with an end quite pointless.
