In later chapters he meets up with some of his less terrible classmates, realizes they're basically sheep/Mob-characters that follow anyone with a personality, and decides to not to kill them.

He was abused as a child to an extent that it's almost unbelievable for an first-world nation. If it did happen, and managed to go unnoticed for that long, his parents would be in jail and he would have been on the news. But somehow none of his classmates knew anything. Most children that survived that sort of torture would be mentally and emotionally crippled, but the MC is just heavily scarred.

The washroom was behind the inn.
It seems that the washroom is semi-outdoors.
The day is about to end.
However, there was still a lamp on a pillar that I could use as a light.
This place also had a tarpaulin on the eaves of the roof.
I look around the washroom.
This place had the atmosphere of those self-service coin-operated laundromats.
Well, there are none of those convenient laundry machines here.
There are several clothes lines that stretched out in the room attached from one wall to the wall opposite of it.
There are already some clothes that were hanging on the clothes line.
If we're talking about carelessness, this should be one of them.

the slime. It just came out of no where and was so forced just to drive the plot and have him get a pet slime for some reason.

The goddess who summoned the heroes is disgusted in the protagonist because he is an E rank, so she comes with a plan to use him to further her plans or whatever but her plan is to sacrifice an E rank by sending him to some dangerous ruins in front of his class. This seems like the most ret*rded plan, I mean that's not how you show your future heroes that they can trust their goddess I mean all she did was create a rift between the heroes and her

but somehow all the other students expect one ate it up because idk their superiority complex came out and curb stomped their common sense.

The MC has joined together with the elf in the cover, and not in a romantic way, more as a companion-ish way. And so far 4 major things happened

• MC gets sent to dungeon
• MC gets out of the dungeon as an OP (pressumably) level 1200+
• MC Encounters Main Heroine (pressumably)
• MC joins together with the Main Heroine.

Ofc its other minor stuff happens too but theyre not really worth mentioninh but I'd say we've just finished arc 1 at chapter 70 which kinda rounds up to a volume length in light novels.

Why? Because I realized that the only thing the MC needs to be unstoppable (exceptuating the goddess) is an artifact powerful enough defensively to make him resist at least 3 seconds or a person powerful enough (Elf-chan) to protect him for the few seconds it takes to say a word.

In chapter 82 we can say that he has already killed the strongest personage in the world (apart from the goddess and maybe the heroes or the goddess servants) with two words "Paralyze" and "Poison".

So... Until the last boss (probably the goddess) notices he is alive, he should be able to do anything he wants without real danger.

This is a story (82 chapters in) where there is no real fighting, he just needs time enough to say "Paralyze" and that's it.

Take a look at sougou, the supposedly very kind girl, whose only reaction after knowing her fellow classmate was sent to the hero slaughterhouse was saying to the goddess she disapproved of her actions, that's it, no comments about how everyone except for her didn't move a finger as the innocent MC was sentenced to death in front of them. There also were people encouraging the goddess to do so, there was even a guy who tried to blast him before MC was teleported. Wtf man, this is what I'm trying to say, its like everyone in this novel has some extreme personality disorder, I tried to feel at least a bit of empathy with these characters through 37 chapters but they just keep acting like bugs in the matrix instead of human beings.

The MC meets the FL in vol. 2 (?) (she falls first), but they are not an item per se, until vol. 5's end.
