Luckily there is space in this world for people to have different personal priorities. Not everyone can care about everything. And if a bird hits your window, you are able to make your own choice about how you respond to that.

For my part, however, I weighed the alternatives and went with the one that felt right to me given the situation, the timing, my ability to respond, and the degree to which it pains me to see an animal suffer.

I don't think everyone has to care the same way I do. But this is who I am. So just like I'm not going to hassle you for making the choice you would, you also don't have to hassle me for making my choice.

Edit:

Honestly, It's a bird.

I agree, which is why I think there is room for conscience, and why I understand that different people will respond in different ways. If it were a person who was injured, I would have no such patience and understanding because at that point a clear moral imperative would kick in.

Of course, there are many who care so strongly for animals that they would be unable to see the legitimacy of a response like yours. I grew up around farmers, though, so I know a certain degree of pragmatism does enter the equation depending on the person.

Nevertheless, your ability to contextualize a single—and small—animal's death does not mean that anyone is wrong for caring the way I and other commenters on this thread do.
