yes,hate is reasonable,in our country, one 32yo married professor pretend a 27 unmarried teacher, cheat and having sex with a teenage girl 16 yo, that's make me sick too. It's happened july.
And i believe eye for eye ,teeth for teeth .Someone needs to pay for his actions, not for something that didn't happen. You can watch him not kill him.If someone feels remorse and takes action, we have the right to choose whether to accept it. Jesus tell us should having more mercy,no more hate. Hate is normal,but its destroy the man nor change him.
