According to my understanding, the system makes a single instance of our servlet and then creates a new thread for each user request.
When the a specific request is completed, will the thread that handle that request being deleted? Why?

Once the request ends, the servlet assigns the thread to process the next request.
When a system removes a servlet, it runs the servlet's destroy method. However, When the destroy method runs,  other threads might be processing service requests.

- Thread handling is not a part of Servlet specifications, so the behaviour can vary for different Servers.

- Most Servers do maintain a pool of threads for the request, here is a excerpt from Tomcat documentation

At server startup time, this Connector will create a number of request processing threads (based on the value configured for the minProcessors attribute). Each incoming request requires a thread for the duration of that request. If more simultaneous requests are received than can be handled by the currently available request processing threads, additional threads will be created up to the configured maximum (the value of the maxProcessors attribute). If still more simultaneous requests are received, they are stacked up inside the server socket created by the Connector, up to the configured maximum (the value of the acceptCount attribute. Any further simultaneous requests will receive "connection refused" errors, until resources are available to process them.
