How did the good Samaritan show love for others?

The Jews did not like the Samaritans.

When the priest and the Levite saw the man who had been attacked they passed by and did not help. The Levite and the priest were Jews and they were not willing to help a fellow Jew.

The Samaritan however helped the Jewish man who had been robbed and dressed his wounds and took him to an inn to recuperate. He even went to the extent of paying for the Jews stay at an inn and offering to pay any extra expenses the next time he passed by.

He showed love by having compassion for someone who hated his people.
