Honestly, I don't feel sorry for these people at all. The Wall means "STAY OUT!" It's a Law Enforcement tool that we have every right to employ in enforcing our immigration laws which no legislative body has voted to change.
You can feel sorry for the death of people, even if you think they acted foolishly or broke the law. These people was likely pretty normal people, and in a better world they wouldn’t have tried to climb over the border wall. A country have a right and duty to enforce control over its territory, but it doesn’t make the people like these people bad people.
