The very idea of the time machine itself being so dangerous to operate is enough to make anyone think hard before deciding to use it.In a similar vein, jellified Mayuri from a later episode.The rest are most likely either lost in space or underground where nobody will ever find them. This is a lot worse in the visual novel because it's revealed that the 14 discovered were the only ones found.

The Jellyman report, with pictures of the jellified humans who were used as time machine test subjects (pictured).And considering some of the horrific and nightmarish things that happen unbeknownst to him in his world. While the story ends on a very happy and upbeat note, with everyone including Kurisu alive again and reunited, Time Travel never been invented, and SERN/Other Countries never getting their hands on it to start World War III, the fact remains: if something were to happen such as World War III starting some other way, or Kurisu/Mayuri/any of Okabe's other friends dying somehow, Okabe can no longer fight against what fate has in store for him anymore. The fact that after Okabe makes the final jump to the Steins Gate worldline, whatever major events in it occur from here on out are basically pre-determined and unavoidable due to the Attractor Fields that reside on this new worldline (and Okabe witnessed many times throughout the story up to the end that you can't really alter these).The only bright side here is that Moeka, despite being a Rounder, is significantly nicer to Okabe since Okabe stopped her from committing suicide in the past, in which drives Moeka to turn the favour back to him. And in the future of this timeline? He is effectively known as the dictator of Japan under SERN as Hououin Kyouma.

As things got better, it is revealed that Okabe in this timeline is in fact a Rounder who works for SERN and is The Mole in his own laboratory along with Moeka.

Okabe's disturbed reaction into that fact in the drama CD portrays the situation perfectly. After separated for a long time, Okabe eventually realized that Mayuri, in fact, is suffering from cancer which drives her into various chemotherapy sessions that effectively drains all her hairs.

The Y2KMillennium Bug turned into a reality in this timeline, which created a massive catastrophe that killed both Okabe's and Mayuri's families.

While some world lines can be rather innocent such as the Delta world line (being the main setting of Darling of Loving Vows), the Gamma world line (from the Gamma Drama CD), in particular, is so horrifying that Okabe decided not to spend any more time in it.

And let's not getting into the more unpredictable world lines when compared to Alpha and Beta.

It feels like gaslighting in its truest form. Even worse, the changes between some world lines can randomly happen from having a person to change their gender and a city area never being rebuilt in the first place (Akihabara stays as an electronic device market district instead of the Otaku mecca in one timeline).

Although the differences between some world lines may be inconsequential and not life-threatening (such as Okabe losing a lottery in one world line and winning it in the other), other world lines may involve someone dying an early death in one world line and surviving it in the other.

Even before getting into the darker parts of the whole story, the idea of being the only one who can perceive the change between world lines and timelines can be a discomforting thought, since most of the time, the changes can be so random and unprecedented, and only that person who can perceive such change.

The only difference that makes the red herring puzzle more acceptable, in my opinion, is that you’re at the beginnig of the game and you only have 3-4 objects to offer.

The hint is a pun based on the english language.

the pump need a monkey wrench, and you have a monkey in the shape of a wrench.

You have a hint: the troll asks for a “red herring”, and you have a (no quotes) red herring.

you need to use the item not as itself, but in a figurative sense.In both puzzles you don’t just pick it up, you must strive to get the object you need (distract the gull / distract the monkey).It’s really obvious that you have to use something with the pump, something you couldn’t use anywhere else, even if you don’t know the term “monkey wrench” (which I didn’t as a kid). Seems much more straight forward than the monkey wrench puzzle to me. It’s really obvious that you have to give him something, you couldn’t use anywhere else, even if you don’t know the term “red herring” (which I didn’t as a kid).
