The ansible script to find ec2 instances with certain tags and terminate them. Does not uses ec2 dynamic inventory script.

        instance_ids: "{{ item }}"
        state: 'absent'
      with_items: "{{ ec2_instances }}"

does not work..does not target the instances with the specified tags
did this work for you?

This script was written a long time back. But its still working for me. Did you update the vars to reflect your environment?

The Filter EC2 instances task not required anymore, ec2_remote_facts now supports filtering.

As with latest version of ansible this is working for me searching by the Name tag but could be any key.

    ec2_instance_facts:
      region: "{{ region }}"
      filters:
        "tag:Name": "{{ ec2_tag_name }}"
    register: ec2_list

They have renamed facts to info.

- name: collect list of node instances
  amazon.aws.ec2_instance_info:
    region: "{{ region }}"
    filters:
      "tag:Role": "node"
      "tag:Vpc": "{{ vpc_name }}"
  register: ec2_list
