Rikki-tikki fought to protect his human and animal friends, and the cobras fought to defend their garden territory and their young. The events of the plot are created by the protagonist battling the antagonists. The final fight creates the climax of the story and ends the conflict.
Nursing an flood-affected mongoose to harbor in his home, Teddy's father let his son keep the small animal when he showed no aggressive signs. Time went by, and things seemed to be going okay; Rikki would come in and out as he pleased, and guard over his son at night. But when the two cobras (Nag and Nagaina) had snuck in their home to presumably kill him, his wife and their son, he was more than proud of the mongoose when Rikki killed one snake and chased the other out of the home.
The idea that supports the claim that smaller offices are more honest than big ones is the last one, that small communities have more incentives against crime. The reason for this is that if a community has more incentives against crime than another, it is more likely to be more honest as crime is related to dishonesty and this is something the small communities try to avoid.
