Buddha said compassion, so if you put snakes here and frogs there, will your life be in danger? Doesn't it mean indirect murder?

Letting go is really not a simple matter. Buddhism has never said that practitioners should be released, but Buddhism says don't kill or raise!

Release can only be accomplished by fate. It is understandable for anyone to encounter such a thing. Everyone has a compassionate heart and can't bear to be killed, hoping to save his life! But nothing is accidental. If this life dies in this way, then the person who saved it may be doing something bad! Because it may be time for reincarnation, and next life may be reincarnated as a human being. Doesn't this hinder his life arrangement? In addition, if this life does anything harmful after being saved, the consequences will be borne by the person who saved it, such as saving a dog and then releasing it. If it bites someone else, the consequences will be mainly on him, so it is best to adopt it after saving it, and not let it go out and do anything casually! Of course, many people now set free for a purpose, thinking that setting free can accumulate virtue and help to cultivate Buddhism. In fact, this is persistence. If it really destroys the ecological balance and people's normal life, then unknown merits will still be created!

Of course, some NGOs protest against killing dogs and other animals, which is a sign of love. It's a matter of ordinary people, only causality. Maybe this is the arrangement!

Therefore, the specific analysis of specific problems cannot be generalized, but as a practitioner, it is better not to do such things artificially, because it is easy to turn good things into bad things if you don't see this karma clearly!
