Answer: to portray Huck’s father as uneducated and ignorant.
In this excerpt, Twain most likely uses humour to highlight the absurdity of the father's sentiment. This is done in order to portray Huck's father as uneducated and ignorant. The father tells Huck that he does not see the importance of school. Moreover, he thinks school is damaging because it will teach Huck to feel superior to his dad, who is unlikely to have attended school.
No they will not......
this is because after seeing caesar's ghost brutus may have some feeling of guilt.....guilt that caesar had loved him so much but he had betrayed him......that guilt will not let brutus fight willingly towards the opponents or maybe some other feeling in brutus's heart that to fully pay for this guilt he must die or he must kill himself......he might perform suicide ......after brutus's death caesar may also want to kill himself due to immense guilt of separating such friends and doing sinful deeds........
making the decision to march the army to Phillipi early after seeing caesar's ghost may have been too fast for such a big decision which would affect the probability of brutus and cassius winning the battle.....
