From Parveen’s conversation & the flashbacks shown yesterday I don’t think he ruined / killed many lives rather one specific family’s life.
The people in the flashbacks he hugged them & caused their plane to crash. Could it be Roshni’s parents ? Did he get them out of the way to become rich. How does the Jinn figure in all this & where is Abu now.
Another thing why put her in a basket why not directly drown her in the river.
Is it a technical blooper or he only wanted to get her out of the way. He wasn’t interested in killing her.
