He gets betrayed by Gilbert and left to die, then when Gilbert is trying to fight an overpowered enemy, he accuses MC of trying to steal his prey only to be overwhelmed, Gilbert is then forced to beg MC for to save him doing the typical 180 on MC telling him he was wrong and begging for help, of course the MC's childhood friend says to leave Gilbert because he got into the situation and it would be impossible for them to help, as there are several high level monsters, but guess what MC says nah f*ck it and jumps in to save Gilbert, saying he never wants to see him again and to leave. Due to plot he barely survives only with the help of the demon sword and his childhood friend.

You'd think he be more wary of people because of his experience with Gilber but no, I sh*t you not, in about 10 chapters after saving Gilbert, he gets invited into another party and guess what, he gets betrayed again this time and guess what again!!! He spares him albeit that in this instant it is because royal guards turn up and take the bad guys away, but MC had ample amount of time to kill and even the sword demon said to kill the bad guys but MC hesitates and is like ehh I'll take my time and reminisce about our time together.

This light novel is the most typical stereotype fantasy there is, MC is too trusting and too nice, leaving him in situation where his friends would definitely have died because of his foolishness. He doesn't learn and is still alive only because of the demon sword, another thing that adds fuel to the fire is that this is pretty turning out to be a harem too! He's saving girls left and right and putting bad guys in their place only because of plot.

Don't read this, I suffered a little trying to like this only to be angrier and more disappointed with every chapter

I don't mind MC's that refuse to kill. I'm not an edgyboi, and don't read CN novels for that very reason. That said, I cannot get behind the MC being betrayed by Gilbert, then having his "revenge" be that he slams the table at a restaurant and says "don't talk to me ever again, bucko!" The MC has the nerve to act like that was some sort of win for him. The author explains (in excruciating but well-reasoned detail) why the MC is forced to do nothing in this situation, and why he has to let it go. That's fine. Just don't act like this is some sort of victory over the dude that almost got you killed. I guess the author got some complaints or something, because 10-20 chapters later, the MC implies that he's not satisfied leaving it there, but it felt out of character since the MC was already established as your typical doormat. I'm calling it now, that any revenge on Gilbert will probably be done in the background by a third party (monsters, another adventurer, the military, his own greed) and will not be cathartic in the slightest or that the author will just plainly forget about him.

Gilbert's betrayal was okay, but the one with Fredo (or whatever his name is), was done so poorly, I actually laughed out loud when he betrayed the MC. I mean the author introduced a strong character out of nowhere, with a kind personality (in a setting that admonishes kindness), and has him invite the "weak" MC to a dungeon capture with a tsundere airhead (read "harem capture target"). What do you think is gonna happen?

Then the author spends 5 chapters telling us that the MC feels something's off, but can't explain it after F-kun kills a trio of PK-ing bandits super easily, even though this supposed trio had been wiping the floor with high level adventurers (and the author will not let this go unheard since he repeats it ad nauseum).

Then F-kun turns out to be the true bandit! Woah! What a surprise! The author sure got me with that one!
