Boston Bombing aftermath, any similarity to the Lincoln assassination aftermath?

[Linda Anderson]

I am reading reports on how the younger Boston bomber suspect partied with his classmates after the bombing.

Does anyone think that Powell would have felt remorse in attacking the Seward household had he met with Booth right afterwards and they had managed to escape?

Do you think if Powell had met up with Booth that he would have felt bad that he had NOT succeeded in killing Seward like he said he was ordered to do?
