REASONABLE SENTENCE?

i think month ago
read a pc of news
a fight broke out over a bowl of $2 noodle......

wife of the bully told the hawker to help cut her noodle and to separate the chilli from the noodle
hawker told her want so many things over a $2 ONLY noodle
bully found out
confronted hawker
bully took chair to hit hawker
hawker picked up a knife and in the commotion, "chop"
bully's thumb kana chopped off

became a police case
investigate
and then hawker jailed and fine.......

i think, many ppl will be like me, hawker only protecting himself
the bully was much younger and bigger size than hawker
and bully came with the chair, hawker just protecting himself, with anything tt is near him at tt pt of time
can't be he take a tissue paper or the table cloth or noodle or throw fishballs at him rite????

anyway, there is a reason for sentencing to a day's jail and a fine
but...what abt the bully??
he got his thumb attached back in the end.....
is tt scar gg to his "punishment" for the rest of his life?????

imagine tt bully was an ex taxi driver
being so hot and quick temper
he exchanged blows with the hawker
imagine, he buay siong his passengers, wa kao!!
i really cannot imagine and dun want to think abt it
*faint*
