Charlie Sheen: 'I'm HONORED' They Killed Me with a Train

It took a freaking TRAIN to kill off Charlie Sheen on "Two and a Half Men" -- and the Warlock tells TMZ, he wouldn't have it any other way ... in fact, he's "honored" by his gruesome, untimely demise.

As we previously reported, Charlie Harper's death on "Men" is absolutely grotesque -- we're told he gets run over by a subway train in Paris, after slipping off the platform, and BLOWS UP in a massive "meat explosion."

But Charlie Sheen isn't just unfazed ... he's elated -- telling us, "I am honored that it took something as large and violent as an oncoming train to terminate my character."

He adds, "Anything less would have been an insult!"
