I play D&D-5e online on Roll 20 with a friend and some of his friends.
Recently in the campaign, a member of our party (neutral alignment) (ab)used his position of power among nobility to get a racist farmer who lived next to MajorCity arrested, and executed, after the farmer refused to house us in a time of need. A week or two later, the party opened a portal over MajorCity, flooding the place with demons and evil entities and causing a mass evacuation of the city.
I was not very pleased with the actions of the other players, even though they argue that their characters had good reasons for all of the above, including not knowing their actions would open the portal (which is kind of true).
My character at that point died in a particularly difficult encounter shortly afterward and the DM had me roll up a new one so that I could join the party at the next town. Between sessions, I have made a character that is the son of the farmer, who was recently orphaned and is seeking revenge. My idea for this character is for the party to be able to make up for their actions. I have set up several ways that the party can "redeem" themselves and avoid conflict.
I don't want to create a role playing handicap for the party. I have asked some of the members privately and not all of them like my character ideas (particularly one of the members whose actions directly lead to the portal being opened) but others have expressed great excitement about my new character.
I've been trying to talk to my DM about my concerns but haven't managed to get ahold of him yet. So I ask you all:
How can I avoid being a handicap roleplay-wise?
(I'm happy to answer any specific questions you might have about my character, the setting, or the group.)
