(we/us pronouns) as a hobbyist naturalist, we choose not to harm or kill (and often try not to handle or interfere with) observed species. We have associates who are much more advanced than we who will collect only deceased specimens for further examination, dissection, identification, etc. Obviously, some protected sites might prohibit collection, but where allowed, we think your own value system will be the key determinant (and it can change over time). We would not try to tell you what to do, however. We appreciate your curiosity, your need to learn and contribute as well as your need to respect.
