The videos are truly horrific.
I saw one where Priyantha Diyawadana was cowering in fear with blood on his face (alive).
Then another on the ground with his face being smashed in, surrounded by a hooting and baying crowd who proceed to kick, beat and drag his stripped body through the streets.
The mobs are filming everything with glee. There is a policeman in front of the burning body and he does nothing.
This is not the first case of people being tortured and killed for "blasphemy" in Pakistan.
I remember reading about Shahzad Masih and Shama Shahzad, a Pakistani Christian couple who were burned alive on blasphemy charges by yet another mob in 2014. She was apparently pregnant too.
So even Pakistanis who are not Muslim are not safe. This is probably one of the reasons that Sri Lanka is home to Pakistani refugees including Shias, Ahmaddiyas and Christians. Priyantha didn't stand a chance once he was accused of blasphemy and a mob was rallied.
Zooming out of this incident, Sri Lanka has extended the hand of friendship to Pakistan over and over again and Pakistanis are well regarded despite the fact that in real life there is little people to people contact between the two countries. This stemmed from Pakistan's support to defeat the LTTE, the training of military personnel in Pakistani academies (such as the current president of SL) and the support the Pakistani cricket team gave Sri Lanka when westerners boycotted the island over security concerns.
I don't think there will be political consequences (the state to state relationship) between the two countries but there will definitely be (there already is) a rupture in the Sri Lankan psyche when it comes to Pakistan. The Easter Sunday attacks on churches and hotels in Sri Lanka that left more than 250 people dead is still raw in the minds of many. Seeing gory videos of a fellow Sri Lankan being tortured, beaten and burned by a Muslim mob in Pakistan has just added even more suspicion and horror.
