I don't know about that first page though, seems like it's just some empathy lacking mudslime encouraging symbolic mass murder.
To kill those who do not conform to your beliefs is more an right hand path thing to do in my eyes. It does not destroy "the system" as the system is often responsible for the deaths of it's own people. The elites are the true psychopaths, only a crazy person would mimic them.
The LHP would applaud the rise in so called "degeneracy" in the western public as sexual liberation spites the RHP ideas of staying "pure" and "uncorrupt".
If you let the external world anger you then you are doing LHP wrong. It is supposed to be introspective spiritualism.
I know part of the point of the left hand path as things aren't as set in stone as RHP but I personally draw inspiration from the myth of Lucifer/Prometheus. Be a bastion of compassionate free will, show others how they can live happier lives through embracing pleasure and giving up routine.
