It depends on whether you want your Mewtwo to be a physical or special attacker. While Mewtwo has a higher special attack than attack, it has a high enough attack stat that it can be run as a physical attacker as well. If you want it as a physical attacker, then yes, it would benefit greatly from knowing Psycho Cut.

No, you cannot because Swampert cannot be taught Cut.
Easily Rayquaza. One you defeat all 16 gyms you can find Mewtwo in the same cave north of cerulean that he was in in the first gen games. To get Rayquaza you must beat all 16 gyms, then beat Red on Mt. Silver, then talk to Mr. Pokemon on Rte 30 to get the Red or Blue orb (depending on whether you are playing HG or SS). Then go to the embedded cave south of the safari zone and catch either Groudon (SS) or Kyogre (HG). Then you have to get whichever of those you didn't catch from another game (only the Groudon and Kyogre from HGSS will work for this) until you have both of them and then go back to the embedded cave, where you will find Rayquaza. Now if you are talking about which is tougher to beat/catch, again Rayquaza. Mewtwo only knows 1 move that can damage you, Psycho Cut. If you bring a Dark type Pokemon there is no way Mewtwo can hurt you.
Pretty good!
Zoey's Gallade has used Magical Leaf, Psychic, Signal Beam, Psycho Cut, Swords Dance, and Vacuum Wave.

Since it's a fighting/psychic It should kind of be like this Sword dance Psycho cut Close combat Ice punch/stone edge *DO NOT TEACH IT SPECIAL ATTACK IT WILL BE USELESS!!*
First you have to get all the kanto badges ( which can't be obtained if you didn't beat the Pokemon league ). Then, the guy in front of cerulean cave will move and in the deepest part of cerulean cave mewtwo will be there at level 70. His attacks are Power swap, Guard Swap, Psycho Cut, and Amnesia.
You should teach HM moves to a pokemon that you will not be using, as you can't forget HM moves until you get to a move deleter. Grass type Pokemon's can usually be thought cut.

not if its an accident
You have to beat the first gym and then you'll get the HM cut. Just teach the HM cut to one of your pokemon. :)
