An ethical tutor won't write the speech for you. If you were to use a speech written by another person, that would be plagiarism. That said, a tutor can give you pointers on things to consider.
Understand the meaning of the quotation and state it in your speech. Is it to be taken literally? For instance, does the fact that a peaceful protester for democracy in Hong Kong is arrested and put in jail mean that champions of democracy in Japan are being treated unjustly? Or should the quotation be understood more figuratively to express the empathy we might have for a victim of authoritarian oppression?
Take a position. It'll probably be easier if that position is supportive of the quote.
Use a couple of specific examples to illustrate the principle.(how the mistreatment of someone has a negative effect on others who are not connected).
If possible, end with a conclusion. Should we be doing something when we know justice is being denied somewhere else in our state? in our country? in the world?
Practice you speech to get comfortable with it and to make sure it sticks to the 2-minute limit.
