Is this the cruellest prank ever?

American prankster Roman Atwood, 32, has racked up more than seven million views of his “blowing up my kid prank” YouTube video since uploading it to the site on Sunday.
The clip shows Atwood road testing a quad bike with Kane, one of his two sons. He then is seen talking to his partner Brittney Smith before deciding to purchase the bike.
Atwood is seen by viewers telling Kane to hide while Smith goes to the car to get a cheque.
He swiftly puts a look-a-like dummy — wearing the same clothes as Kane — on the bike.
As Smith returns, Atwood appears to lose control of the quad bike — which is operated by a remote — and it zooms off with the dummy on the seat, flies off a ledge, and bursts into flames.
Smith runs and screams for her son who she believes is in the fireball.
She soon clues on to the prank as she approaches the explosion site and sees the dummy.
“It’s not funny, that’s not funny,” Smith said as she kicks Atwood.
“Don’t touch me, I’m done. I’m done honey, I can’t do it.”
Atwood grins and seeks reassurance.
“You still love me right?”
Some viewers described the prank as “the funniest thing ever” while others said it was “sadistic”.
“This isn’t funny, that’s just sad,” one YouTube user wrote.
But it’s not the first time Atwood has been behind a controversial prank.
His other videos include “The Kidnapping Children Experiment”, “The Public Rape Experiment” and “The Killing My Own Kid Prank” where he throws a dummy disguised as his five-year-old boy off a second story balcony in front of the child’s mother. That video has been viewed more than 26 million times.
Some viewers questioned the authenticity of the videos and said Smith was acting.
Smith has previously commented on Atwood’s pranks and said she wasn’t “in on them”.
“Oh no, there’s no way I could have been in on that,” Smith told Inside Edition.
“I was trembling. I’m not an actor, I’m a stay-at-home mum. There is no way I was in on this.”
Smith said she wasn’t bitter.
“You can’t live with a prankster and not expect to get pranked,” she said.
Atwood’s other pranks include pretending to confess to Smith that he cheated on her and posting an image of her on Instagram where she appeared to have drowned
And, earlier this year, he joined forces with fellow prankster Yousef Saleh Erakat to carry out the ‘suicide prank’.
They detailed to taxi drivers how their lives had turned for the worse before requesting to stop on a bridge and scale a security fence, appearing to prepare to jump.
The drivers, clearly distraught, talked the men down before Erakat and Atwood confessed that the prank was being filmed and that they were never going to jump.
Some viewers were moved by watching perfect strangers intervene but the video was slammed by many for “experimenting” with such an emotional issue and for driving viewers back to a website selling merchandise.
The pair’s videos include links to romanatwood.com or “The official Smile More store” where merchandise including shirts, hats, pens and even toothbrushes are sold.
“This is not an ‘experiment’ of any sort, just like the rest of their ‘experiments’. These are carefully scripted videos intended to be heartbreaking because stuff like that easily gets viral and accumulates millions of views. More views equal more money. They are not trying to spread any messages or raise awareness, they are purposely playing with people’s emotions because that brings them money,” one viewer wrote.
Atwood reportedly has a net worth of more than US$3.5million from his online pranks.
