Ok, so if anyone's wondering the reason why rna mutates so frequently is because it is single stranded(our dna is double stranded) so it doesn’t have a second copy to use as a template to fix any damage to the rna. And other various reasons like high replication rate hence more mutations faster. (Of course there's other reasons like lack of proofreading and instability but this comment is too long)
Also, I hate people who can just kill/hurt for entertainment or attention, I hope MC can stop them before it happens or get some evidence to incriminate them(which is easy since they're livestreaming this?)
