as i tend to believe in a resurrection on earth not a "spiritiual afterlife", there might be punishment for the wicked on earth, but im not sure how logic that is
It's not illogical at all. Nor is it un-biblical. The law of reaping and sewing is in full effect. Not in another life, but in this one. Belief in (UR) turns up the heat on us to be holy as He is holy. Paul points out in 1 Corinthians 6 that we are to be perfected here in this life so that we may be counted worthy to judge the world. There is a calling out there for a remnant who will be set apart as priests and kings.
1 Corinthians 6
1Dare any one of you, having a matter against another, prosecute his suit before the unjust, and not before the saints?
2Do ye not then know that the saints shall judge the world? and if the world is judged by you, are ye unworthy of [the] smallest judgments?
3Do ye not know that we shall judge angels? and not then matters of this life?
4If then ye have judgments as to things of this life, set those [to judge] who are little esteemed in the assembly.
5I speak to you [to put you] to shame. Thus there is not a wise person among you, not even one, who shall be able to decide between his brethren!
6But brother prosecutes his suit with brother, and that before unbelievers.
7Already indeed then it is altogether a fault in you that ye have suits between yourselves. Why do ye not rather suffer wrong? why are ye not rather defrauded?
8But *ye* do wrong, and defraud, and this [your] brethren.

He is talking to believers who are expected to become holy as Christ is holy here in this life. Not some far off place or time. So, believing in (UR) does not give us an excuse to do nothing. On the contrary, it reveals the true purpose of our existance here; to become holy as Christ is holy right here and now.
