The Warrior Returns

What happened to SH family is sad. It is depressing. Yet, that does not give him the right to take other's happiness. Other uninvolved people. However, it seems a LOT of people agree, sympathize, support and even justify his actions.
He could like a normal person, ask for help. Family and friends are not the only place to ask for help.

Basically, following the rationale given by the SH supports I cam eto the conclsion of the type of people we should support; and I mean support all their actions regardless of any harm to others.
(1)Let us start with Bullies. We should support them, and even encourage them so that they keep on making life miserable for others, before killing them.
(2) Terrorists- because they have big weapons.
(3) People who no longer have any one in their life due to unforeseen accidents( eg- natural disasters).
Let me be clear, following rationale provided by the SH and his supporters; for (3) we should allow, and even encourage them to kill every single being alive. That includes the supporters and their family too, probably. They are not to be provided help or counselling, weapons and a killing spree is the answer. All should be according to what their guide the SH said- if I'm sad then everyone else should be sad too.

this is what happens when a psychopath became magaka.. mass murder just cuz he's sad XD
on top of that the crazy amount of plagiarism
The only good thing here is the art but that can't save this trash

I wanted a genocide, but instead I just got your usual factory made generic MC righteous, and upright

The mangas characters are completely unmotivated to commit the acts they do, everyone is just a psychopath and kills everyone for fun... If a mangas character have no rime or reason for their actions other than "im evil now" then why would the reader become emotionally invested. This manga is extremely boring since it's story is subpar at best because its completely unrealistic in how people act in the real world...

Lets say i was Isekaied, i spend 8 months fighting and subsequently killing the demon lord, i then get to go back home. Now imagine once i get back home 8 months have past and my parents have died because of either accidents or deep depression of losing their child resulting in suicide, the rest of my family hates me and i feel abandoned, do i -A- try to cut out a new life for myself seeking meaning and an escape from my depression with my incredible powers that i still have, effectively build a new life... or do i -B- kill everyone around me (millions of innocent people) because "if i'm sad then everyone else should be sad to"... if you chose B then this manga is for you...
