slashing is good in a way that blockchains that are using this mechanism their validators are much careful because they know that if they would try to manipulate blockchain or do any malicious behaviour than there stake tokens would be cancel out which would be very detrimental for them financially so it is a way to have more honest validators

Yes definitely I extremely agree with your question that if slashing would be in use then validators would take more precautionary measures so that they may not lose anything overall I really like your comprehensive comment at my entry I wish you success in your participation which I have already visited and it was really really informative and good
