Beware From IAGO

hi everyone,
last night i was reading a book of shakespeare OTHELO , it was a love story drama but most of it is a double crossing and hating drama. we find a great example of double crossing.
there is a character named IAGO . He is lier , dishonest, double crossing person and we can give him all negative titles.
then i thought about around me and about in the world and i find a lot of IAGO in around me.
when one IAGO can make so much distruction then a lot of IAGO can make hell our world and our life .
so beware from IAGO.
