Am I wrong??
You're right, but someone making the choice to intercede on behalf of others is also right. This is a VERY personal decision, because it boils down to the individual identifying what they are or are not willing to risk their physical, emotional, financial, legal, and moral well being on. Nobody has the right to tell another person what they should die for.
What is actually selfish is one person acting entitled to have another person risk life and limb for them.
