Going mad is the worst thing that can happen to you short of death. It is a terrible, shattering experience, not a cliche-ridden Oscar-grabbing thrill ride of hammy acting. Don't approach it as an opportunity to get wacky. Respect it for what it is: the ultimate betrayal of your own mind.
Insanity is the failure of your rational side. It is the death of options. It is when you cannot choose between reasonable paths because you can no longer judge them.
Madness is what you see when you've got nothing left to fall back on.
