"would" in this sentence
hi, would you please help me with this sentence which I read from an article.
I find myself in complete agreement with them with regard to experiments for cosmetic purposes. I cannot think of a single item of toiletry which WOULD justify pain or death to an animal.
1. does it because it's an assumed situation, the author could not use "WILL" here?
2. can I use "COULD" or "MIGHT" instead of "WOULD" here?
