My Reaction to the Post-Feast of Sacrifice (Eid al-Adha) Aftermath in Bangladesh

Just thinking about all that blood in Bangladesh is so scary I wouldn't upload the pictures here. After reading the The Guardian which just disgusted me further:
Rivers of blood flow on streets of Dhaka after Eid animal sacrifices 
Poor drainage in city has meant that blood has combined with rain to form red floods in Bangladeshi capital. 
Animal sacrifices as part of the Islamic festival of Eid al-Adha have combined with rain in Dhaka to form rivers of blood in the streets of the Bangladeshi capital.
Poor drainage in the city makes flooding a regular fact of Dhaka life. But the problem is rarely illustrated as vividly as it was on Tuesday, after thousands of sheep, goats and cows were slaughtered.
One of the two holiest events in the Muslim calendar, Eid al-Adha commemorates the willingness of the prophet Abraham to sacrifice his son at God’s request.
Authorities in Dhaka said they had established hundreds of designated sacrifice spots in the run-up to the festival to make it easier to clean away blood and animal carcasses.
But local media said most residents eschewed the special areas, preferring to make sacrifices in their garages or on the streets outside their homes. 
The result was a nightmarish blending of blood and water that filled streets and narrow lanes across Dhaka from Tuesday morning. 
“I felt I was walking through a post-apocalyptic neighbourhood,” said Atish Saha, a Dhaka-based artist. “To be honest, I was scared. It was an image of mass violence that shouldn’t ever be experienced.” 
Particularly jarring was said to be the sight of families, including infants, wading into the flood in celebratory “Eid day” moods. “It made me speechless,” he said. 
Saha said the ritual slaughter was continuing in parts of the city on Wednesday. The waters had mostly receded by the morning but bitumen and dirt roads still had a reddish hue and were littered with animal entrails.

My reaction is that even after all the animal sacrifices that were made, it only made Bangladesh look like the water was turning into blood like in the Ten Plagues of Egypt. The problem is that Islam still relies on pilgrimages. It doesn't want the finished work of Christ. Here's what the Bible says:

Hebrews 9:11-13 - But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; neither by the blood of goats and calves, but by His own blood he entered in once into the holy place, having obtained eternal redemption for us. For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
Hebrews 10:10-12 - By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: but this man, after He had offered one sacrifice for sins for ever, sat down on the right hand of God;

God already provided the only sacrifice that can remove sins and it's the Lord Jesus Christ. That sacrifice ended the need for animal sacrifices. All this unnecessary bloodshed could have been avoided only if they accepted the perfect sacrifice of Jesus. Animal sacrifices are biblical but today they're no longer part of the New Testament. The Old Testament is still relevant with the moral law but not with the ceremonial law.
