Are there more natural ways to say the linsentences below?

I'd like to speak English more naturally and not the way you would find insound like a textbook.

It's alright even if you even change an entire sentence!!

I think I have anthe idea that I can only be kind to those who benefit me in some way.

But I have oOne of my goals in life to reduce the number of animals killed to zerois to eliminate the killing of animals.

「But」は必要ではないと思います。

I thought this was not about profit.

I added this to the next line because it sounds more natural to me.

ButI thought this was not about profit because helping them would save me from reliving their painful reality in my thoughts, and seeing them live happily and healthy would eases my heart.

Previously, I was walking through a train station and an oelderly lady asked me for money andso I gave her $10.

「elderly」の方が親切です。

If I did not give her the money, she might be in more trouble more, and I would feel responsible if something bad happened to her.

I don't think there is no 's anyone in the world whom we helped even thoughwould help if there was really no benefit to us.

ちょっと分かりにくいと思うので、添削が違うかもしれません。The double negatives are confusing me.

I don't think there is no such a thing as no-benefit support in this world.

Again, the double negatives are confusing me. In English, we don't use them very much.

I think I have an idea that I can only be kind to those who benefit me in some way.

But I have one of my goals in life is to reduce the number of animals killed in the world to zero.

But helping them would save me from reliving their painful reality in my thoughts, and seeing them live happy and healthy would bring eases to my heart.

PreviouslyOnce, I was walking through a train station and an old lady asked me for money and. I gave her $10.

If I did not give her the money, she might be in trouble moreworse off, and I would feel responsible if something bad happened to her.

In order to avoid such a future, I thoughtink that I understood this reflexively and gave her the money.

In other words, I gave her the money to escape responsibility.

Honestly, I think in this situation you're taking responsibility, not escaping it. Not helping the woman would have been escaping responsibility (I think).

I think there is no one in the world whom we've helped even though there was really nowithout any benefit to uourselves.

Even if there is no real benefit such as "money," the relief or satisfaction or things like that within myoneself is also a benefit to that person.

The nature of a person's behavior changes depending on what kind of benefit is insidethe benefit to them.

I don't think there is no such a thing as no-benefit supportpure selflessness in this world.
