Answer:
My answer won't be perfect since I don't know what reading you did but this was my take on it:
One person can make a large difference in the pool of human rights. Take, for example, the right that all men (and women) are created equally. One person can defend and upkeep this right by treating everyone equally; with respect and kindness. One could also step up for others if they feel as if they are not receiving equal treatment. Personally, I have witness, in the grand scheme we call life, a fair share of hatred and prejudice (in real life and on social media) but I have always seen that hatred and prejudice overcome by an overwhelming amount of love. The calling to stand up for others is precisely what has defended human rights of all people; and it's exactly what will continue to defend human rights for all.
: What is the biggest sin you've ever sinned?
<em>Well, in all honesty, I have done a lot of... questionable and awful things within my life, but, I feel like one of, if not, the greatest sin I've (accidentally) done, was nearly getting someone to take their own life, because of actions I had taken out on them gradually.</em>
<em>For context, we had a very large falling out, and things got very toxic. From petty insults to writing massive walls of text to degrade each other and ruin friendships the other might've had, it was an all-around terrible situation. But, we've both somewhat forgiven each other for the impulse actions we'd done. Although I can't forgive myself outright. I hurt someone close to me in a way I still live down to this day; even if they have forgiven me.</em>

<em>But, thankfully, despite everything that went on, they're still alive to this day, but, I still live with that deep regret I won't forgive myself for. </em>

<em>( I, only hope this answers your question... )</em>
Poverty is God's sign of sin and a blessing of wealth
The contrapositive of the statement "if p then q" is "if not q then not p."
Having this in mind, the opposite of the statement "If dogs have fleas, they scratch all night" is the third option - If they don't scratch all night, then dogs don't have fleas.
