Which lines in this excerpt from act v of romeo and juliet show that romeo feels guilty about having killed juliet’s cousin tybalt?
a- mercutio's kinsman, noble county paris!
what said my man, when my betossed soul
did not attend him as we rode? i think
he told me paris should have married juliet:
b- how oft when men are at the point of death
have they been merry! which their keepers call
a lightning before death: o, how may i
call this a lightning? o my love! my wife!
c- o, what more favour can i do to thee,
than with that hand that cut thy youth in twain
to sunder his that was thine enemy?
forgive me, cousin! ah, dear juliet,
d- from this world-wearied flesh. eyes, look your last!
arms, take your last embrace! and, lips, o you
the doors of breath, seal with a righteous kiss
a dateless bargain to engrossing death!
