Fire, guns or lions? [closed]

A murderer is condemned to death.
He has to choose between three rooms.
The first is full of raging fires.
The second is full of assassins with loaded guns.
The third is full of lions that haven't eaten in 3 years.

Which room is safest for him?

• This is a very old puzzle for kids. I am sure, someone would find a dupe for it... – Sid Sep 14 '16 at 7:50
• oh my ... it would be better if you make it instead of using a old and known one – lois6b Sep 14 '16 at 7:50
• It probably would be, but I found it and thought it was a pretty neat one :( – Foitn Sep 14 '16 at 7:51
• So, starving to death is 'Safest'?, if all the result was death then I'll take the bullet #partypooper – BetaTester Sep 14 '16 at 8:11

Obviously its

The lions who hasn't eaten in three years as it would be dead by now

He would open all the three doors at the same time , the lion would eat the all assassins and later then the lion would jump into the fire , because of the guilt of killing so many people .It had turned into saint lion as it had fasted for 3 years. Then he can go any of the 2 rooms.

I think it's the

Assasins

Let me first clarify a possible loophole in the typical answer:

It could be disputed that "eating" is the process of inputing food in mouth, probably chewing, and then swallowing. There is an alternative: IV. So the lions could be alive without eating by having IVs on them.

If this is a case,

Assasins are professionals and would generally not attack someone without reason.
