Is there any point in going to hell?

Thank you for your question.
The Buddha's teaching is not that people who do bad things go to hell.
The teaching is that people who have done bad things should live their lives so as not to repeat the same bad things from now on.
So what you need to do isn't to go to hell; it's about not repeating past mistakes from now on.
Moreover, the Buddha's teaching is not about doing it perfectly.
It teaches you to make an effort.
It doesn't have to be a 100-point scale.
If you make an effort even at 10 points, the Buddha will praise you.
You can do whatever you can before you even think about going to hell, so please do your best.
Instead of doing bad things to dirty laundry, please run away sweat (cleaning, etc.) and aim for dirty rags by doing good things.

From the Buddha's point of view, neither you nor I can add anything good to humans. Even if you eat just one meal, you have received (taken) other lives and have kept this life alive for a long time. The destination is definitely hell, isn't it?

While being aware of that, I will listen to Buddhism.

I can't get rid of my doubts on my own. The Buddha made a wish for those who have sinned profoundly, and he works for me with the power of salvation.
I think you're looking for salvation.

While relying on the great mercy of the Buddha called Amida Nyorai, who prays that way, I want to cherish the wishes that Amida says and summons, and live my life.

Then, they reflect on themselves and revise themselves so as to respond to the Buddha's wishes and blessings.
A way to live a life of recompense.

Why don't you also receive Amida's will, Namu Amida Buddha?

If there are people who smoke too much and get sick, I don't think there is any particular meaning (merit) of getting sick.
However, as a result of smoking, they are suffering from illness. There are only causes and effects.
However, it makes sense to imagine that if you smoke too much, you might suffer from illness.
If you can anticipate bad results, you can change the cause ahead of time.
Buddhism teaches techniques for erasing and controlling the cause of worry and suffering, and erasing and controlling the consequences of worry and suffering.
Buddhism also explains how to be freed from the Rokudō Reincarnation Incident, which includes hell,
Methods for reducing the worries, suffering, and stress of everyday life are also explained.
In both cases, it's basic to change the cause and change the effect.

I read it. The sight of you judging yourself as “ugly” and worrying and suffering so much that you wish for purification in hell hurts my heart. However, in conclusion as a monk, there is no need to find merit or rehabilitative effects in falling into hell.
This is because Amida Nyorai's original wish is that he will save only those who lament “I'm going to hell,” just like you, as they are.

You said “dirty laundry,” but it doesn't mean you can't be saved unless it's washed in a washing machine called hell and it doesn't turn white. Amida continues to call you, “Be sure to save, leave it to yourself,” even though you are still covered in that affliction. There is no need to wait for your sins to disappear due to suffering in hell; you will be captured in Amida's light while still harboring that current suffering.

The attainment of Buddha by Daibadatta is not an effect of hell, but it shows how deep the Buddha's mercy is. The thought of seeking meaning in hell is probably an expression of anxiety that “we cannot be saved as it is now” if you turn it around.

Please keep listening to Amida's call, which envelops you, saying “You can just leave it as you are,” not your expectations for hell. There's no need for you to go to hell anywhere.
