To put it simply, under the law, although Everett and the Lord of Wind are detestable, their actions don't warrant death.
However, one must view this matter from another angle. Lord Sun, in his previous life, was widely known for the famous anecdote of "Two Peaches Kill Three Warriors", well-known to all, even to women and children. Simmons greatly admires this strategy. Still, what he extolled was not the fact that two peaches caused the death of three brave warriors, but instead, he strongly agreed that the interests of certain individuals could be sacrificed in times of national peril. Although the charges against the three warriors were perhaps trumped up or nonexistent, their influence had already affected the stability and unity of the nation, making their execution justifiable.
